    Update Python library handling (#2317)

This does not include the changes to nrn/src/nrniv/pyenv.cpp (launching nrniv) where the master version states in load_nrnpython

        // It's possible to get this far with an incompatible version, if nrnpy_pyversion and
        // friends were set from the environment to bypass nrnpyenv.sh, and nrniv -python was
        // launched.

dirs_exist_ok keyword arg was added to shutil.copytree in python version 3.8. Should we no longer attempt to build a wheel for 3.7?

Should we no longer attempt to build a wheel for 3.7?

Python 3.7 was end of life more than a year ago (2023-06-27), so I don't think it's needed.

[nrnhines]

I fixed nrn/setup.exe so that it would work for Python 3.7. Mostly because I was thinking the windows installer for 8.2 was being built for python 3.7 to 3.12 and I wanted to keep that behavior. Currently for 8.2, which are the python 3.7 wheels that we attempt to build?

I don't happen to know the answer to that, I was just commenting that there is no longer support from python for 3.7, so I would say it's not needed for others to maintain compatibility with it.
