Standard geographic names

presently, #211 works. However, there may be a discrepancy between the Leaflet openstreet basemap and the GADM data that needs to be solved.

I found more details about the openstreetmaps administrative areas classification. It is nicely documented: https://wiki.openstreetmap.org/wiki/Tag:boundary%3Dadministrative Since this is openstreetmaps, it is also open-source and widely-used. I suggest we drop the GADM fields and use the openstreetmaps fields instead.

NEW 23 Mar 2023: Input of administrative areas should not be required if coordinates are already entered into the sites creation mask. administrative area input drop-downs could appear after checking a box named "Indicate administrative area instead of coordinates"

Thew alternative of using geonames should be investigated: http://www.geonames.org/

Do we just need to unify their names? Do we need to keep the leaflet the same and modify the gadm?

Good question. I looked a bit more into the topic and clarified the first post.
