I hacked together a stack-collapse program for
measureme and it ... seems to work?
btw @Wesley Wiser do you know about https://www.speedscope.app/ a simple frontend for flamegraphs, could be useful. (I'm not sure if prlo would generate flamegraphs but if it was the case, maybe we could also embed it there heh)

Yeah, I've seen some docs for ff but I haven't really gotten a chance to get it working
I have a few commits that add the Chrome version of the tool. I should polish that up and get it merged
