Trentino and Alto Adige may be given different rules

[mmolinari]

Trentino and Alto Adige were given different zones in the past, so it's very possible this will happen in the future too.
In case we need to touch the regions map:

• the region and province maps are here: https://github.com/openpolis/geojson-italy
• this works well to edit the map: https://geojson.io/
• this is able to export a GeoJSON as TopoJSON, choosing the level of detail: http://shancarter.github.io/distillery/
