Python 3.12 support

[BrianJKoopman]

I wanted to open an issue to discuss building Python 3.12 wheels, selfishly because I just updated my personal system to 3.12. Any anticipated issues?

I'd expect at the same time we'd drop 3.7 support, as that's at end-of-life.

When we do this can we also update the compatibility list on PyPI here:

so3g/setup.py

Lines 414 to 416 in 51a8ae3

	"Programming Language :: Python :: 3.7",
	"Programming Language :: Python :: 3.8",
	"Programming Language :: Python :: 3.9",

The last time I investigated this for other packages, there were still some core astro dependencies that were not yet available. That was a few months ago, and it may be that so3g has fewer such dependencies. So it might just work...

pixell does not yet support 3.12. Keep an eye here.

It seems with the release of pixell v0.25.0/v0.26.0 it now supports 3.12.
