Why not use the pint.UnitRegistry (like in NOMAD)? See how I am using it in the pynxtools-xps here.

Actually, using just if isinstance(units, pint.Unit) does not seem to work.
If I do the following
import pint
units = "m"
print(isinstance(units, pint.Unit))
that prints False, so obviously this unit check does not work as intended.
pint.Unit is just a class to implement a unit, not something to be used directly to check a string is a pint unit. We need to use pint.UnitRegistry, like in NOMAD.

@RubelMozumder I rebased this branch on top of master to make it reviewable.
I don't think your check if isinstance(units, pint.Unit) works, see below.

Shall this raise an error or simply be logged as a warning? The file can be written without this wrong unit, right?
