pandas compatibility

[MJoosten]

There seems to be a funny version incompatibility between numpy, pandas, matplotlib and seaborn where the kdeplot function in seaborn (or the histplot function with the parameter kde=True) give a ValueError of the form:
valueerror: multi-dimensional indexing (e.g. obj[:, none]) is no longer supported. convert to a numpy array before indexing instead.

One solution is to maintain the following versions of these libraries where this error does not occur:
numpy==1.25.2
matplotlib==3.7.2
pandas==2.1.4
seaborn==0.13.0
Python==3.10.13

If this reoccurs after re-testing the Paper ipynbs, feel free to update the environment in the pyproject.toml to these versions of packages, run all the pytests and if successful continue to use these versions
