distutils will be deprecated in Python 3.12

[ljwolf]

Across the project, many packages use distutils for setting up installations. However, distutils will be deprecated. We will need to deal with this by moving to pyproject.toml. The best way to do this is probably revise the submodule template to use the pyproject.toml specification, and then propagate that downwards.

This will affect the metapackage, as the metapackage will be uninstallable on 3.12 until all its constituent parts are off of distutils.

We already started the transition in some packages. I think that the latest one was tobler (https://github.com/pysal/tobler/pull/174) but it seems that we will need to do this across all packages before next meta.

Yep, just logging it here because it will be blocking for release.
