Once the data is proccessed delete the original Lat Lon fields from the processed records,
leaving only the GeoJSON (default true)

-dropDestColl
Before starting, drop the destination collection (default true)
-fieldNameLat string
the name of the field in the source collection holding the Lattitude data (default "Latitude")
-fieldNameLon string
the name of the field in the source collection holding the Longitude data (default "Longitude")
-preserveObjectID
When inserting the new document, remove the objectID so the DB can assign a new one
