TST: Test against Python 3.11

[pllim]

Description

This pull request is to see how badly things break in Python 3.11 (using RC2).

Blocked by

• Dependency on h5py causing incompatibility with Python 3.11 glue-viz/glue#2340
• Is this package compatible with Python 3.11 ? astropy/regions#475
  • Update Cython in pyproject.toml astropy/regions#476

No longer an issue

• Python 3.11 wheels h5py/h5py#2146 (glue stopped pulling it for Python 3.11, see Add a check for FITS files mistaken as ASCII to astropy_table_read for Python 3.11 compatibility glue-viz/glue#2321)

Nope... regions and h5py need to catch up first. We can revisit this PR when they do. (So close!)

What is pulling in h5py? We do not use it.

[dhomeier]

Installing (building yourself, probably) h5py for py311 at least at this time, for rc2, requires libhdf5-dev (possibly also libopenblas-dev, but that's probably for numpy/scipy) in the apt libs, and hdf5 from brew.

[pllim]

I didn't mean to build h5py from source. The released version wasn't working but since you said it is supposed to work now, let's see.

[dhomeier]

From what I can tell from the log, it has to build the wheel itself. See glue-viz/glue#2321 for reference.

[pllim]

That is kinda painful for something that we don't even use here.

We can now officially add Python 3.11 to our CI. 😸
