[Very WIP] Thread Visualizer

This is very early in development, but I would love to get some feedback. Run dav1d and open the thread_log.html file. Each row is one frame_offset value (there's probably something better to use) each color is a frame thread.

added tools label

Look into pthread_getname_np

Look into frame_thread waiting

Somewhere I should have a patch that adds hawktracer probes, do you think it would be useful to send it or do you prefer your approach?
