Add two new methods to OpenLibrary for batch fetching entities: - ol.get_many(olids): fetches any mix of Works, Editions, Authors in a single /api/get_many.json call. Returns typed objects; null/missing entries are silently skipped. - ol.get_many_by_isbn(isbns): resolves ISBNs to OLIDs via one /api/books.json call, then fetches full Edition data via get_many(). Two total HTTP calls regardless of batch size. Both methods are tested (9 new unit tests, 55 total passing).

Summary
Adds two new methods to
OpenLibraryfor bulk entity fetching:ol.get_many(olids)Fetches any mix of Works, Editions, and Authors in a single
/api/get_many.jsoncall. Returns a list of typed objects in response order. Documents not found in OL are silently skipped.ol.get_many_by_isbn(isbns)Resolves ISBNs → OLIDs via one
/api/books.jsoncall, then fetches full Edition data viaget_many(). Two total HTTP calls regardless of batch size.Why
Single-entity fetches (
Work.get(),Edition.get()) make one HTTP request per entity. For import pipelines and bulk enrichment, this is prohibitive. The/api/get_many.jsonendpoint already exists on OL and supports hundreds of keys per request.Testing
