Compatiability issue with newer CPython in setup.py

[nevercodecorrect]

Hi,
Thanks for the nice and interesting project.
I am encountering an issue when trying to install Fusil on the latest CPython.
I execute the python setup.py install
But it throws the error that

Traceback (most recent call last):
  File "/lafleur-working-dir/fusil/setup.py", line 91, in <module>
    main()
    ~~~~^^
  File "/lafleur-working-dir/fusil/setup.py", line 61, in main
    fusil = SourceFileLoader("version", path.join("fusil", "version.py")).load_module()
            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'SourceFileLoader' object has no attribute 'load_module'. Did you mean: 'exec_module'?

It looks like a new feature was introduced in 3.12+.
I currently change the setup.py line of code
fusil = SourceFileLoader("version", path.join("fusil", "version.py")).load_module()
to

version_path = path.join("fusil", "version.py")
try:
      fusil = SourceFileLoader("version", version_path).load_module()
except AttributeError:
      fusil_spec = spec_from_file_location("version", version_path)
      fusil = module_from_spec(spec)
      spec.loader.exec_module(fusil)

to support both older and newer versions to make it work.
