Verified Proposed Changes: Update region names and codes per https://fr.wikipedia.org/wiki/ISO_3166-2:FR, as seen in table below. Region codes will be modified for all features, and region names updated where they were changed ( "-" indicates no change) For overseas departments, value for region code is currently department code. Proposing to update these also to 3 letter region codes, to standardize length of codes (FR-XYZ).

I spot checked the changes in this PR and they look great, thanks! To recap: in 2016 the existing French "departments" (what Natural Earth considers admin-1) were regrouped into new "regions" (which NE tracks as groupings of admin-1), so the work in this PR so far establishes the new region names and region codes in the admin-1 data tables. This took the number of enumerated metropolitan regions from "22 to 13". One thing to verify together... this PR should be coherent with the boundary lines, too. (below) Blue lines are department boundaries, red lines are ALSO region boundaries – but are they pre-2016 regions?
Compare with what Wikipedia has for the 13 metropolitan French regions – the NE red lines should match:
This involves changing the featurecla between But it looks like those were changed at some point already? Running Because you're working off the v5-prequel branch you get this change for free (a few months before Arlo was born and I went MIA), even though it hasn't been released yet :) So I'll merge the PR now! |

In admin_1_states_provinces data, the region attributes of French provinces are still in the old divisions. Since 2016 France is mainly divided into 18 new administrative regions: 13 regions in metropolitan France (including the territorial collectivity of Corsica).
