Remove field id constraint on add files

[jeroko]

Rationale for this change

Closes #2131

The PR relaxes the constraint that prevented adding any file with field IDs, and replaces it with a constraint that prevents adding files which contain field IDs that are inconsistent with the field IDs of the table. If the field IDs are compatible, then they can be added safely, if not, they will be rejected.
