1.15.0

In #385, I introduced a dependency on the `uint8array-json-parser` npm package, but used a fork because of a typescript error. This was resolved in evanw/uint8array-json-parser#1 and published as part of `uint8array-json-parser@0.0.2`. Let's use the upstream.

This also conveniently fixes a new typechecking error that was preventing deployment. The error looked like this:

```
src/import/utils.ts(2,26): error TS2306: File '\''/Users/jlfwong/code/speedscope/node_modules/uint8array-json-parser/uint8array-json-parser.ts'\'' is not a module.'
```

After updating to the upstream, the problem is fixed.

+# Contributor Covenant Code of Conduct:
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project
+and our community a harassment-free experience for everyone, regardless of
+age, body size, disability, ethnicity, gender identity and expression, level
+of experience, nationality, personal appearance, race, religion, or sexual
+identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of
+acceptable behavior and are expected to take appropriate and fair corrective
+action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an
+appointed representative at an online or offline event. Representation of a
+project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting
+[jamie.lf.wong@gmail.com](mailto:jamie.lf.wong@gmail.com). All complaints
+will be reviewed and investigated and will result in a response that is
+deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an
+incident. Further details of specific enforcement policies may be posted
+separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.

+# Contributing to speedscope
+
+Hi! This is a short guide & set of guidelines for contributing to speedscope.
+Contributors of all skill levels are welcome to submit pull requests.
+
+This project adheres to the Contributor Covenant [code of conduct](./CODE_OF_CONDUCT.md).
+All contributors are expected to uphold this code of conduct.
+
+## Setting up for development
+
+To start running speedscope locally, run the following:
+
+    git clone https://github.com/jlfwong/speedscope.git
+    cd speedscope
+    npm install
+    npm run serve
+
+This should open up a running version of speedscope in your default browser.
+
+In your terminal, you should see something like this:
+
+    $ npm run serve
+    > speedscope@0.7.1 serve /Users/jlfwong/code/speedscope
+    > parcel assets/index.html --open --no-autoinstall
+
+    Server running at http://localhost:1234
+    ✨  Built in 7.30s.
+
+Most of speedscope is written in TypeScript. If you're unfamiliar with
+TypeScript, then you can either just try to learn it as you go, then the
+[official TypeScript
+documentation](https://www.typescriptlang.org/docs/home.html) may be of use
+to you!
+
+If you're not sure where the code you want to modify lives, the [`README.md`
+in the `src/` directory](./src/README.md) might be helpful.
+
+## Code formatting
+
+All TypeScript code in speedscope is automatically formatted with
+[Prettier](https://prettier.io/). This means that while you're writing your code,
+you don't have to worry about following a formatting guide, because a program will
+format your code for you!
+
+The easiest way to use Prettier is via an editor integration. See the [Editor
+Integration](https://prettier.io/docs/en/editors.html) page from Prettier's
+documentation for help with that.
+
+If you don't want to do that, you can alternatively run the autoformatter by
+running `npm run prettier`.
+
+## Running tests
+
+All TypeScript tests are written use [Jest](https://jestjs.io/). To run the
+tests, run `npm run jest`.
+
+## Contributing new features
+
+Before contributing code to implement a new feature, please open an issue to
+discuss it first. Large pull requests that are submitted without first getting
+maintainer buy-in are unlikely to be reviewed or merged.
+
+For features that will cause a visual change, please include visual mockups of
+the change you're planning on making.
+
+## Contributing bug fixes
+
+If you discover a bug, please file an issue. If the code change required to
+fix it is small (< ~20 lines), then feel free to just open a PR to fix the
+issue without trying to get buy-in ahead of time.

+在 "Time Order" 页面 (默认)，调用堆栈按照它们在输入文件中出现的顺序从左到右排列，这通常是安排它们被记录的时间顺序。这个视图对于理解应用程序随时间变化的行为非常有帮助，比如 "首次从数据库获取到数据，然后为序列化准备数据，数据被序列化为JSON"。 
+
+水平轴表示每个堆栈的“权重”(最常见的是CPU时间)，垂直轴显示在运行期间处于活动状态的堆栈。如果你点击其中一个框，你将能够看到关于它的统计摘要。

+
+在 "Left Heavy" 页面，将相同的堆栈分组在一，不管它们是否按顺序记录。然后，对堆栈进行排序，使每个父堆栈中最重的堆栈位于左侧——因此称为“左权重”。 这个视图对于理解在其他调用栈之间有成百上千个函数交错调用的情况下，时间都花费在了哪里很有用。

-### Firefox
-
-The `profile.json` file format output by Firefox can be saved and import into speedscope: https://developer.mozilla.org/en-US/docs/Tools/Performance
-
-### Node
-
-If you record profiling information like so:
-
-    node --prof /path/to/my/script.js
-
-Then this will generate one or more `isolate*.log` files. You can open
-the resulting profile in speedscope by running the following command:
-
-    node --prof-process --preprocess -j isolate*.log | speedscope -
-
-### Instruments.app
-
-You can import call trees from OSX Instruments.app into speedscope by
-selecting a row in the "Profile" view and select "Edit -> Deep Copy" from the
-menu then pasting directly into speedscope. This data contains only aggregate
-statistics, so the "Time Order" view and the "Left Heavy" view will look very
-similar.
-
-You can also import `.trace` files for time profiles by dragging them directly
-into the browser from Chrome.
-
-### `stackprof` Ruby profiler
-
-If the `raw: true` flag is set when recording a dump, the resulting json dump can be imported into speedscope.
-
-### Linux `perf`
-
-You can import profiles recorded using `perf record` and formatted using `perf script`.
-
-    perf record -a -F 999 -g -p PID > perf.data
-    perf script -i perf.data > profile.linux-perf.txt
-
-Then drop the resulting `perf.txt` into speedscope, or if you have speedscope installed
-locally, you can run:
-
-    perf record -a -F 999 -g -p PID > perf.data
-    perf script -i perf.data | speedscope -
-
-### `DTrace`
-
-If you process the output of `DTrace` first with Brendan Gregg's `stackcollapse-*.pl` scripts (https://github.com/brendangregg/FlameGraph#2-fold-stacks), the result can be imported into speedscope.
+Contributions to add support for additional formats are welcome! See issues with the ["import source" tag](https://github.com/jlfwong/speedscope/issues?q=is%3Aissue+is%3Aopen+label%3A%22import+source%22).

 ### 🕰Time Order
-
-In the "Time Order" view (the default), the stacks are ordered left-to-right in the same order as the occurred in the input file, which is usually going to be the chronological order they were recorded in. This view is most helpful for understand the behavior of an application over time, e.g. "first the data is fetched from the database, then the data is prepared for serialization, then the data is serialized to JSON". This is the only flame graph order supported by Chrome developer tools.
-
-In all flamegraph views, the horizontal axis represents the "weight" of each stack (most commonly CPU time), and the vertical axis shows you the stack active at the time of the sample.

 In the "Left Heavy" view, identical stacks are grouped together, regardless of whether they were recorded sequentially. Then, the stacks are sorted so that the heaviest stack for each parent is on the left -- hence "left heavy". This view is useful for understanding where all the time is going in situations where there are hundreds or thousands of function calls interleaved between other call stacks.

+## Source Map Test Project
+
+This directory contains test files used to test whether the remapping of
+performance profiles using sourcemaps work correctly.
+
+Run `npm run build` to build the artifacts, then open the appropriate files in
+the `html` directory in whatever browser you're testing.
+
+The idea is to sourcemaps generated by a variety of tools, and also to take
+profiles from a variety of browsers, and hopefully see that they all get 
+remapped as expected.
+
+This project is set up to go through three levels of source-map indirection,
+and also using multiple different build chains.
+
+1. TypeScript -> JavaScript source generation
+2. JavaScript source -> JavaScript bundling
+3. Minification
+
+Some bundlers will swap the order of steps 2 & 3, or potentially merge them,
+but it's complex yet realistic enough that this will hoepfully suss out 
+problems.
