`InCollection` CITATION entry not mapped

InCollection CITATION entry is not mapped to a schema.org @type.

This is probably just a matching error, “InCollection” vs. “Incollection”. Better to match on lowercase, I suppose? I can open a PR with a fix.

Relatedly, could/should booktitle, editor (and isbn), i.e. info about the book that contains the chapter, be included via [isPartOf](https://schema.org/isPartOf)?
