There was a problem hiding this comment.
I've never used a big endian system so this is probably a dumb question, but on big endian systems, won't these bits be backwards? (Ie, wouldn't this need to be 0b0000_0011?)

This PR makes the encoding for the string table more compact, as described in measureme::stringtable's module-level documentation. It also moves the code for reading string tables into the
analyzemecrate.This PR concludes my planned changes to the file format for the time being. We'll need some more changes to the API in order to facilitate recording query keys but those should not require updating perf.rlo.
It's probably best to review the first commit in isolation.
