Python 3.12 support

[elagil]

With the release of Ubuntu 24.04 LTS, Python 3.12 is shipped.

Currently, cmsisdsp cannot install on it, due to it using the deprecated distutils.
The same is true for some dependencies (e.g. numpy 1.22).

I can create a PR, but it will require to update dependencies as well (e.g. to numpy 1.26).

@elagil Thanks. I have a PR about Python support that have been pending forever.
I need to find some time to work on the Python support and correct all those problems.

If you point me to the other PR, I can work on it. We need that support at our company, so I can spend a bit of time on the topic.

Would you be open to move forward to the (somewhat) new way of defining python packages? See https://peps.python.org/pep-0518/

The former setup.py or similar will be replaced by a pyproject.toml in the process.

@elagil The PR : #148
I just need time to merge and test ... time that I have unfortunately not found so far :-)
I can switch to the new pyproject.toml ... I just need to still be able to support Python 3.9
