Leave "Chr" value as string when parsing

Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi

* The "Chr" value seems to be mostly a name of some sort, despite it being,
  seemingly an number. This commit parses the "Chr" value as a string.
  It also updates the tests to expec a string, rather than a number for "Chr"
  values.
