This file must be moved to the fatcat:python/ directory (aka, not in

quickly. There are no tests.

Fixup script for bootstrap longtail OA release entities which don't have a

Expected to be a one-time fixup impacting about 600k entities (around half
the longtail OA batch).
Reads in a mapping of unique domain-ISSNL mappings, and then iterates over
the original matched import batch file. For each line in the later:
- checks if in-scope based on domain-ISSNL map
- uses API to lookup file (by SHA-1) and confirm domain in URL list
- look up releases for file and retain the longtail-oa ones (an extra flag)
- if release is longtail-oa and no container, set the container based on
ISSN-L (using cached lookup)
- use EntityImporter stuff to manage update/editgroup queue
