LoC-> TMS style name mappings for contributors and subjects

[yulgit1]

It appears that our LoC to TMS name form transformations have been applied only to the creator field. Compare, in these library records:

• Peter Blake as creator, name transformed: https://collections.britishart.yale.edu/catalog/orbis:12462655

• Peter Blake as contributor, name not transformed: https://collections.britishart.yale.edu/catalog/orbis:10175074

• Peter Blake as subject, name not transformed: https://collections.britishart.yale.edu/catalog/orbis:16026575

Applied now to contributor and subject:
