Python 3.13 support

[larsoner]

Didn't see an open issue, what's the reason for not supporting 3.13? Looks like mpython-core supports it:

https://github.com/MPython-Package-Factory/mpython-core/blob/1651f7bd2105da1b2ec0d622bd946aa3142ca692/pyproject.toml#L14

... in particular, I don't really think that this package specifically needs a version pin unless this package is doing something incompatible with 3.13 (or likely to be incompatible with 3.14, 3.15, etc.). If this package depends on mpython-core and that package has a version pin, then that's fine, this one will effectively inherit it when users try to install it. But by having version pins in both packages means that both packages need to be updated any time one of them is, which is a bit more painful than just letting mpython-core handle the pinning issues directly (esp. if those are related to MATLAB somehow, better to let mpython-core handle it!).

Hi @larsoner, thank you for raising this up!

The reason for limiting the support of this package to Python <3.13 is the dependency to the spm-runtime, which contains the CTF file built through Matlab Compiler SDK and is only compatible until 3.12 (see Matlab documentation).

I agree with you regarding putting the pin in a single place. We are currently working on the installation pipeline, and this restricted compatibility should move to the spm-runtime, which is the only piece of code tied to a particular Python version. For now, our efforts have mainly been on making installation through Pip easy, but we are keen on expanding.

Happy to hear your thoughts!
