Support Python 3.12 and Django 5.0

[mgax]

• Add Python 3.12 and Django 5.0 to the testing matrix.
• Bump maximum versions of numpy and scipy to versions that can be installed in Python 3.12.

Looks good to me. I don't think anyone would argue with dropping support for Django <4.2 going forward if that's something you need to do for e.g. feature support/maintenance simplicity.

@mgax could you please add the Django 5.0 trove classifier too?

Maybe we can open this up and make this <2

(Would be even more awesome if we could move the entire 'winner' calculation which requires these dependencies to the database and drop the need to install these heavyweight dependencies. Maybe some future day...)

Since we're using a tiny bit of the numpy/scipy APIs, this does seem like a low-risk change. I've loosened the constraints.

Awesome 🚀
