build: allow Numpy 1.X

[RobPasMue]

Can we not allow NumPy 1.X? This is breaking the rest of the ecosystem @koubaa

ansys/pyansys#764

[RobPasMue]

DPF is working on making that upper limit more flexible but setting a minimum of 2.X is pretty constraining

[RobPasMue]

This will require a follow up patch release

@RobPasMue

the Ci/Cd still installs numpy 2.0
the problem with numpy 1.x support is with hollerith, it only works with numpy 2.x.

This PR will allow the pydyna-solver, pydyna-pre, and pydyna-run submodules to work with numpy 1.x, but not the pydyna-keywords module. maybe we can throw an error in the __init__.py file of the pydyna-keywords module until hollerith can support both numpy versions?

NEP 29 doesn't indicate an end-of-life date for numpy1, so I guess we have to fix hollerith so it supports both versions, and test both in the ci/cd. I'll file an issue there.

Works for me. I can add that disclaimer/check. Is there a big limitation on the numpy version for hollerith?

@RobPasMue see ansys/hollerith#34

[RobPasMue]

We might have a bigger issue ... hollerith will force us to install numpy 2.X still whenever we pip install... making the warning totally useless. We need to get that one solved first.

Agreed. I may need a bit of help there

[RobPasMue]

This will allow to use Numpy 1.X now... releasing right after CI/CD passes
