make: *** [install] Error 2

Some collaborators are having a difficult time even installing py-ard with pip install on their machines because of this error - the wheel for numpy 1.24.3 fails to build with this different error related to ImpImporter.

It's currently a bit of catch-22. If I upgrade numpy to numpy==1.26.4, it doesn't work withpandas==1.5.3, it requires pandas>=2.0.0 but this then breaks py-ard.

I'll try and figure out the issue with Pandas.

[lgragert]

It is still perhaps true that "py-ard works with Python 3.8 and higher," but that cannot be accomplished with a pip install alone on Python 3.12.

It's getting tougher to the thread the needle on setting up a suitable Python environment, so incompatibility with Pandas 2.0 is becoming a practical barrier to usage. Good to prioritize that.
