Use OAM as imagery source

[robsavoye]

If possible, use OpenArialMap as the imagery source for the basemapper.py program.

OAM reverses the order of the xyz values in the database from most other map tile servers use. I have this now working in a branch in order to produce basemaps for the Turkey earthquake, but it needs to be cleaned up and the result tested to make sure it doesn't break other imagery sources.

This has already been complete via the --tms flag and works:

e.g.

pdm run osm_fieldwork/basemapper.py -b
 New_Kru_Town_MERGED.geojson -d $PWD -o New_Kru_Town_Basemap.mbtiles -z 12-20 --xy=True 
-t https://tiles.openaerialmap.org/5e6785161804990005e37072/0/5e6785161804990005e37073/{
z}/{x}/{y}
