Pull Request Checklist:

• [x] This PR addresses an already opened issue (for bug fixes / features)
  • This PR fixes issue #320
• [x] Tests for the changes have been added (for bug fixes / features)
• [ ] Documentation has been added / updated (for bug fixes / features)
• [x] HISTORY.rst has been updated (with summary of main changes)
• [x] I have added my relevant user information to AUTHORS.md

What kind of change does this PR introduce?:

• Uses platformdirs to set a default platform-dependent location in the event that one is not provided for local_weights_dir.
• platformdirs now handles the caching location for testing data.
• require_module now handles supported module version information.
• Fixed the version pinning and comparison code for xarray (2023.03 → 2023.3)

Does this PR introduce a breaking change?:

Yes. The default location hard-set in the roocs.ini configuration has been removed.

Additionally, the .clisops_testing_data folder can be removed from your $HOME folder. This is now saved to $HOME/.cache/clisops on *nix.

Other information:

On Linux, this looks like:

from clisops.core.regrid import CONFIG

CONFIG["clisops:grid_weights"]["local_weights_dir"]
>>>'/home/my_user/.local/share/clisops/weights_dir'

@Zeitsperre @sol1105 when using platformdirs could we skip the roocs.ini config for weights_dir?

[Zeitsperre]

@cehbrecht I suppose you technically could. I've set it up so that if the option is not provided, it'll use a cached location, but if you'd rather remove this option entirely, you should be able to work with locations provided uniquely by platformdirs.
