Add ISBN citation support to reference/provenance

[stappan]

User Story: Curators often use books in addition to digital references to provide context and source experimental evidence for neuronal populations. We need to be able to list books as sources. Identifying the chapter and page would also be ideal.

Acceptance criteria: ISBN numbers are either 10 or 13 numbers long (ISBNs assigned on or after January 1, 2007 are 13 digits long, while those assigned before 2007 are 10 digits long).

@tgbugs and @iliasziogas can you please review this request to support book citation? Are there additional criteria or existing format that we should utilize? Tom, I think there are books ISBN stored in neurondm (e.g., see https://composer.scicrunch.io/statement/468 ) but I'm not sure if this is formalized? thanks!

The way I handle isbns right now is as a uri with the following prefix -> namespace mapping.

{'ISBN13': 'https://uilx.org/tgbugs/u/r/isbn-13/'}
# I don't have a prefix for ISBN10 right now but could add one

e.g. ISBN13:9780393972832. However I don't do any validation to make sure there are actually 13 digits.

Trying to go more granular than that in a formal way (structured) is not a good idea right now because there are no standard conventions for how to reference chapters, figures, page numbers, etc. (crazy right?). My suggestion is that any more fine grained references be put in curator notes, or better, uploaded as e.g. a screenshot of the figure.

Thoughts?
