fix compatibility with NumPy 2.0.0 (dependes on a fix in `python-quantities` package)

[slayoo]

For now, we need to restrict NumPy version to <2.0.0 due to a problem with chempy (bjodah/chempy#234) that actually originates in an incompatibility with NumPy 2.0.0 of the python-quantities package (python-quantities/python-quantities#232)

Stale issue message

@slayoo should we close this since mentioned issues are also closed?
There is a TODO flag in examples/PySDM_examples/Arabas_et_al_2023/figs_3_and_7_and_8.ipynb, we can then delete it.
