[FEATURE] Publish ROR data dump as CSV (in addition to JSON)

[lizkrznarich]

Describe the problem you would like to solve
GRID previously made its data dump available in CSV, as well as JSON and RDF. For those who previously used the GRID CSV, those looking to import ROR data into a SQL database, and those who would like to interact with ROR data without having to parse JSON, it would be useful also publish ROR data dumps in CSV.

Note: This issue covers the CSV portion of the work described on ror-community/ror-api#113 . The RDF portion on issue 113 will be addressed separately.

Describe the solution you'd like
Initially, we will produce a single CSV with a subset of fields (those that are not deprecated or empty in all records). The structure of this CSV is different from GRID CSV files; ROR does not use a database for curation, so we will not include a full_tables directory.

id
name
status
types
established
country.country_name
country.country_code
addresses.geonames_city.id
addresses.geonames_city.name
addresses.geonames_city.geonames_admin1.code
addresses.geonames_city.geonames_admin1.name
aliases (delimited list in one field)
acronyms (delimited list in one field)
labels (delimited list in one field)
links
wikipedia_url
external_ids (GRID, ISNI, Funder Registry and Wikidata only, as columns with [id name].preferred and [id_name].all as headings)
relationships (delimited list in one field)

Who would benefit from this feature?
Developers, Librarians, Researchers; others who wish to use ROR data without parsing JSON
