WIP: Exclude accessions where geo.uncertainty > 20000
In AccessionGeo the uncertainty declares how "bad" the coordinates are (in m meters). Such accessions should not be included in GIS functions of Genesys.
Add a constant ACCEPTABLE_COORD_UNCERTAINTY = 20000 (20km). Latitude/longitude of accessions with uncertainty over this constant must:
- Not be included in the map tiles generated by Genesys
- Not display the map in the website UI (the data should be displayed)
- Excluded when lookup is done by lat/lon from UI
- PDCI calculator should assign 0 value
