Bump numpy dependency to Numpy 2.x

[janheindejong]

Awesome package!

However, when I try installing it on Python 3.13 it fails, since the package depends on Numpy 1.x, and there's no wheels for this version of numpy and Python on PyPi. It tries to build Numpy, but this requires all kinds of difficult dependencies (gcc).

Could we bump the Numpy dependency?

It works on Windows. Not sure what issue you’re having. The dev version supports numpy 2, but also 1.x. I see no reason force users onto 2.0.

Hmm... interesting. When I check PyPi for the latest version of Numpy 1.x, I can't find any builds for CPython 3.13 and beyond.

https://pypi.org/project/numpy/1.26.4/#files

If I'm not mistaken, this means that if you want to use PyNastran, you either have to stick to Python 3.12, or install all tools needed to build Numpy from source.

Yes. Python 3.13 did not exist when i released 1.4.1

The standard for Linux is to use the package manager

Ok. I guess it's fine for now, but in 2-3 years time I can imagine being stuck on 3.12 for Windows users will start to hurt.

I’m working on a new release but I work 70 hour weeks and pypi is harder than it used to be.
