The `units` field of my schema is not being parsed

[vtnate]

All other fields are parsed as expected. Is there something special about a units field? This is the schema I'm reading. Perhaps unsurprisingly, I'm not using jsonschema2md directly, but rather using https://github.com/magicaljellybeans/mkdocs_schema_reader which is using v1.3.0 of jsonschema2md.

FWIW, when I run jsonschema2md directly, it still doesn't include the units field. What can I do to get that field to be included? I didn't see anything in the json-schema docs to suggest that units was special or was deprecated or anything like that. I've tried various json-schema versions to no avail.
