No module named 'pkg_resources'

[MichaelClerx]

Describe the bug

Pystan can't be imported if setuptools 82 or newer is installed.
Instead, it raises

  File "/home/michael/dev/pints/venv/lib/python3.12/site-packages/stan/model.py", line 18, in <module>
    import stan.plugins
  File "/home/michael/dev/pints/venv/lib/python3.12/site-packages/stan/plugins.py", line 4, in <module>
    import pkg_resources
ModuleNotFoundError: No module named 'pkg_resources'

This was long deprecated: https://setuptools.pypa.io/en/stable/pkg_resources.html
And has now been removed: https://setuptools.pypa.io/en/latest/history.html#deprecations-and-removals

Describe your system

Python 3.12, with Setuptools 82

Steps/Code to Reproduce

Install PyStan, install setuptools>=82, run below

Code Sample, a copy-pastable example

import stan

Hi, pystan is not currently actively developed. I recommend using CmdStanPy.
