LP#1553287: Add part information to biblio.fingerprint

Evergreen metarecord searching will sometimes group together different works
that are part of the same series because biblio.fingerprint doesn't incorporate
subfield n or p from the title. For example, bib records for the Mockinjay
movies list the Hunger Games in the 245a with Mockinjay in subfield p.
Without the part information in the fingerprint, Evergreen will group these
movies together with versions of the first Hunger Games book.

This branch adds parts subfields to biblio.fingerprint to allow us to
distinguish among different parts in a series.

+Bibliographic Fingerprint Improvement
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+The bibliographic fingerprint will now incorporate subfield n and p from MARC
+title fields to better distinguish between records of the same series that
+may share the same title but have a different part. With this change, these
+MARC records will no longer be grouped together in a 'Group Formats & Editions'
+search.
