remove distutils

[ocefpaf]

It is imported but unused (tests passes without it). Removing this import will make cf_xarray ready to Python 3.12.

Edit: Changing to packaging.version.parse is not the same thing as LooseVersion, see https://discuss.python.org/t/add-looseversion-to-pypa/24359/6, but we should be OK b/c here b/c the packages checked all follow PEP440.

Cool thanks! I copied that from xarray, so if you could change it there, that would be great too!

Will do. The sooner we get rid of distutils the better, or we will see tons of dumb breakages when moving to Python 3.12.

Looks like someone already implemented the necessary changes in xarray.
