Versions of requirements are too tightly fixed

In principle, there is no showstopper to run iop4 with the latest Python version 3.12 (3.13 coming already in a few months) other than some requirements above that need to be updated as well to make installation possible. I ran iop4 tests with Python 3.12 leaving dependency versions free (e.g. setting "matplotlib>=3.7.1" instead of "matplotlib==3.7.1"), and it worked.

Still to be thoroughly checked though. But something to keep in mind.

I think we first should improve test coverage by a good deal, then progressively free dependencies, to make sure nothing inadvertently breaks. Patch versions are probably fine anyway, although I remember that some of them at least were to avoid some bug.
