Jamie Wong 1987e83bde Upgrade libraries & change release procedure (#8)
Previously, I was doing a hacky release process where I had `index.html` serve contents for `jlfwong.github.io/speedscope`, but used `dev.html` locally. This seems like it broke with the latest parcel release, so I just revamped the release process instead.

Now, the `release.sh` script creates a temporary shallow clone of the repository, overwrites its contents with build artifacts, runs a local server to verify it's working, then commits and pushes to the `gh-pages` branches.
