Use importlib.reload instead of imp.reload (Python 3.12 compat)

[musicinmybrain]

In aeidon/test/test_locales.py, use importlib.reload where available (Python 3.4 and later) instead of imp.reload; the imp module has been deprecated since Python 3.4 and is removed in Python 3.12, so this is a Python 3.12 compatibility fix.

The fallback to imp.reload is preserved since README.md claims support for Python 3.2.

Thanks, I had not noticed this.

Could you please change it so it uses importlib.reload only and update the Python requirement in the README too. I don't in general like cluttering code with these version-specific branches and in this case I doubt the README is correct anymore. I have most likely already broken Python 3.2 compatibility unknowingly at some point and by now that should be fine.

Sure, I’m even happier with that approach.

I’ve updated the PR to disclaim Python 3.2 and Python 3.3 support.

Thanks!
