review old ontology IDs that do not resolve to InterLex

[tgbugs]

There are a number of identifiers in https://github.com/SciCrunch/NIF-Ontology/blob/dev/ttl/generated/NIF-NIFSTD-mapping.ttl that have no corresponding entry in https://github.com/SciCrunch/NIF-Ontology/blob/dev/ttl/generated/NIFSTD-ILX-mapping.ttl nor in https://github.com/SciCrunch/NIF-Ontology/blob/dev/ttl/generated/NIFSTD-SCR-mapping.ttl.

@tmsincomb We need to review these and make sure that they resolve. IIRC there is already code that does this or could do this with little additional work in https://github.com/tgbugs/pyontutils/blob/master/nifstd/nifstd_tools/mapnlxilx.py.
