possible to sample python cpp extensions ...? #370

Wondering if there's anyway I could get pyinstrument to see into cpp callstacks ... I like pyinstrument and the fact that it can be started up within process.

Even if this feature was difficult to achieve in general -- I'm wondering if there might be a way I could hack together something simpler that would work for my specific codebase. In my codebase, I use nanobind to define an extension module in cpp, and all time spent within is a result of a python function call (python calls into cpp, never the reverse).

I could also conceivably add some code to my python -> cpp callsites to try and make this analysis more feasible ...
