_atom_type_scat.versus_stol_list. This item will be overhauled to return its compatibility with DDL1 (see #216).
_refln.form_factor_table. Here the units seems to depend on the type of radiation. If I correctly understand the dREL code in case of "neutron" we end up with femtometres and otherwise we end up with none. So maybe we could have a Definition method that assigns units based on this criteria (as is already done in the case of _refine_diff.density_max_su).
Closes #409.
Specifically, this PR changes the units of some data items to 'unspecified'. The items in need of this change were taken from the a comment by @rowlesmr in issue #409 (https://github.com/COMCIFS/cif_core/issues/409#issuecomment-1574719776).
However, I did not modify two of the items:
