Add support for Python 3.13

[lucas42]

Python core removed modules aifc and sunau in 3.13 as part of PEP-594 https://peps.python.org/pep-0594/
This change adds standard-aifc and standard-sunau as dependencies for python 3.13 and above. These are forks of the modules that had previously been in the python core.

Also updates the test config to run against python 3.12 and python 3.13

Fixes #144

Tests also require stardard-chunk and standard-audioop, the latter of which is not currently available from pypi.

@Kangie where is chunk being used? Can't see any references to it in the repo.

Yes, looks like audioop might be a problem. I can see one place it gets used:

audioread/audioread/rawread.py

Line 133 in 577f8e2

data = audioop.lin2lin(data, old_width, TARGET_WIDTH)

Perhaps it's worth using https://github.com/AbstractUmbra/audioop for that instead. (standard-audioop never got created because it's not a pure python library, see youknowone/python-deadlib#6 for details)

[Kangie]

It came up when trying to update the gentoo package, possibly an indirect dependency via either sunau or aifc that's come up trying to invoke them in the test suite?

Sorry in the middle of a huge system update, but I did stash the ebuild I was using where I added it as a dependency:

https://github.com/Kangie/gentoo/blob/283c7d14199454342c7be9e4ab00650f15cb5583/dev-python/audioread/audioread-3.0.1.ebuild

Honestly if we're up to 3 or 4 "dead batteries" I wonder if it's better to find proper replacements for all of them. These were dropped for a reason after all and this is just a band-aid fix.

That does sound reasonable. However, personally I don't know enough about low-level audio file modification to be able to contribute much to that endeavour.

Tests also require stardard-chunk and standard-audioop, the latter of which is not currently available from pypi.

I've dug into this a bit further. Both standard-aifc and standard-sunau include audioop-lts as a dependency. (Sorry, I should've realised that was the case - looking at the commit history, I was the one who added it 🤦 ).

Running the tests in github actions appears to work for me: https://github.com/lucas42/audioread/actions/runs/11599693327/job/32298399085 (there's some warnings thrown, but no errors).

@Kangie are you running tests and/or pulling in dependencies differently to how it's configured in the github workflow in this repo?
