Segfault #62

I seem to be getting a segfault when python code tries to callback into or return values to Javascript code.

Seems like it is related to deno_python missing these important calls:

c.PyEval_InitThreads()
or
c.PyGILState_Ensure()

My environment is bunjs on Ubuntu Jammy WSL 2.
Also happens sporadically on another machine which is a MacBook Pro M1.
