Support for Async Generators

[catwell]

Is your feature request related to a problem?

Currently encountering an asynchronous generator ends the stack. That is because they are not introspectable.

Describe the solution you'd like

I would like the ability to view a full stack containing Async Generators.

Describe alternatives you've considered

I made a proof of concept to show it can be done with ctypes. Not sure you would consider this in aiomonitor proper.

Additional context

I had that need while debugging code using httpx which is basically a big stack of Async Generators.
