Python 3.12 support

[NathanCummings]

Hi, as far as I can tell, this fails on Python 3.12 as netcdf.py imports distutils which was deprecated in 3.10 and removed in 3.12. Could either:

• pyproject.toml be updated to reflect the fact that >3.11 is not supported.
  or (ideally)
• The incompatible code be removed to enable 3.12+ support.

The intake2 branch (#147 ) is aiming to modernise this repo, and most of the functionality is covered in the main intake package. I haven't had much change to work ont he PR, lately. Would you like to test-run it?

[NathanCummings]

Yep, I'll give it a whirl.

FYI, pip install . with a python 3.12 venv (created using uv) required 2 changes in versioneer.py.

See the changed lines marked with a blue marker.

This was a bit interesting, as from my reading of the docs, these features were renamed back in python 3.2, so I'm not sure how they found their way here or how it hasn't caused problems before.

Probably versioneer itself can be updated by many version points - but switching to setuptools-scm might be more current. I am happy to include your changes, however, if it's the quickest way to make things consistent.

[NathanCummings]

Agree with both, but the after watching one of your talks about intake2, it feels like this plugin shouldn't even be necessary anymore?

[martindurant]

Indeed, this is more of an attempt not to loose existing intake-xarray users, and their v1 catalogs, even if they upgrade to intake2.

As can be seen from the code, it's easy in most cases to map v1 sources to v2.

Has this been fixed by #147?
