Description
#902 got rid of dependency version checking in init.py (apart from for cfdm)
However, it could still be done cheaply with the importlib.metadata module (as pointed by @sadielbartholomew: https://github.com/NCAS-CMS/cfdm/pull/362#discussion_r2491190645):
>>> from importlib import metadata
>>> metadata.version("cftime")
'1.6.4'
>>> metadata.version("netCDF4")
'1.7.2'
>>> metadata.version("dask")
'2025.7.0'
So, do we want to do this?
Related, is making sure that our libraries return nice things in this manner.
This issue should have the same solution as https://github.com/NCAS-CMS/cfdm/issues/364
