This was added few weeks ago, didn't realise it was mentioned here...

With new relations we can now add multiple different geometries to one admin, here we are changing modeling for localities to always have point and in case it also has polygon adds it via new Area type which references Locality via `localityId` property.

Also renamed `maritime` to `isMaritime` and moved to `defs.yaml` in `admins/`
Also added to `locality.mdx` text mentioning where to get polygons, to help new comer faster understand this pretty important information when looking at admins :)

Tristan raised concern regarding what would landmass version of polygon represent, simplified area or not(because not simplified is very big and complex geometry) and all this can be calculated by user by removing Coastline from maritime Polygons...
Hence let's have broader discussion over next few weeks which polygons we want to include in Overture...
