Jamie Wong 6d4f3499da Fix import of multithreaded Chrome profiles (#194)
In #160, I wrote code which incorrectly assumed that at most one profile would be active at a time. It turns out this assumption is incorrect because of webworkers! This PR introduces a fix which correctly separates samples taken on the main thread from samples taken on worker threads, and allows viewing both in speedscope.

Fixes #171
