[ANN] PythonCall and JuliaCall

[cjdoris]

@Paul_Soderlind

do I avoid getting a new python installation/download if I set (for instance), JULIA_PYTHONCALL_EXE="C:\\miniforge3\\python.exe"
before installing PythonCall?

Yes, selecting an interpreter explicitly opts out of all the automatic dependency handling - nothing will be downloaded. This means installing any required packages is up to you.
