add orcid and ror to namespaces

[timothypage]

We talked a while ago about using this codelist as the dropdown for the Contact > External Identifiers namespace (which translates to ISO 19115 partyIdentifier namespace) and adding orcid and ror to this list.

This may need some conversation, possibly with users. Looking here: https://info.orcid.org/brand-guidelines/#the-orcid-name and here: https://ror.org/display-guidelines/ and the pattern of usage in the codelist, It might look something like this:

• orcid.org | ORCID | "desc"
• ror.org | ROR | "desc"

This scheme would allow building a pathname from the code and the number, without interpreting the coding. Hilmar may have some ideas on this.

I concur with @dwalt. Based on the maintaining organization guidelines and consistency with other items in the code list, I would recommend:

• {code: "orcid.org", codeName: ORCID, description: "ORCID identifier"}
• {code: "ror.org", codeName: ROR, description: "Research Organization Registry identifier"}

This also closes #36

Since we're updating the list we should also add:

• {code: "spatialreference.org", codeName: SR-ORG, description: "Coordinate reference system from SpatialReference.org database"}

The above was identified by and would also close #35
