pySPM support under Python 3.13

[ns-rse]

Describe the bug

pySPM depends on skimage<0.21.0,>=0.20.0 which are from 2023.

However under Python 3.13 this results in the issue described at KeyError in _regionprops.py during Documentation Installation (debug) in Python 3.13 · Issue #7585 · scikit-image/scikit-image.

Traceback of attempting to load the module is...

❱ python3 -m righttyper -m pytest --continue-on-collection-errors

E   KeyError: 'area'

As noted in that issue it is resolved in skimage>=0.25.0 which was released 2024-12-13

Would be great if the pinned dependency on skimage could be removed so Python 3.13 can be supported.
