Normalize: add all derivatives to the database

In order for later microservices (like Transcribe) to see normalized
files, they must be tracked in the database. This tracks all normalized
files and their derivations in the database, but skips adding new
PREMIS events in order to avoid cluttering the METS file.

Assign file UUIDs: provide option to disable filegrpuse override

This is necessary to deal with certain places where meaningful
filegrpuses have already been assigned, and overriding the values
makes it impossible to correctly track these files in the METS.

This also updates the "assign file UUIDs to metadata" microservice to
avoid clobbering fileGrpUse, in order to leave transcriptions'
meaningful use.

CreateMETS2: don't treat all text/ocr as Dspace

This fixes the organization of OCR files produced by Transcribe.
