Add support for organization information

[briri]

We are in the process of adding organization identifiers to the DMPRoadmap codebase, specifically ROR and FundRef. It would be useful to somehow incorporate these into the Common Standard schema.

Perhaps something like:

"affiliation": {
  "name": "University of Virginia",
  "abbreviation": "UVA",
  "url": "https://www.virginia.edu",
  "affiliation_id":  {
     "type": "ror", 
     "identifier": "https://ror.org/0153tk833" 
  }
}

This could then:

• be added to the contact and contributors as affiliation
• replace the current name and funder_id on the funding object as funder
