[ ] Be able to run perf (or similar) from code (likely backed by a C++ fn)
[ ] Port the stackcollapse-perf.pl to jank so we can collapse stacks
[ ] Use clj-async-profiler's generate-flamegraph for the rest
We likely can't pull this whole thing in as a library without patching it to be cljc and using reader conditionals; start by copying the code, if that's easier
[ ] Might need to implement spit for writing out the file
