v0.6.32

This release holds more weak glossary names in corpus adopt and adds two sources. Corpus adopt holds a glossary entry whose one-word name only qualifies a noun, such as Unitary or Brauer (#575). It also holds an entry that is only a name, an entry that defines a property, and a heading with a slash between two names (#576). The zbMATH Open Knowledge Graph has an adapter, and a dump resumes after a read error (#563). Open Library gets the lineage of the Library of Congress MARC records (#574).
