Exclude rows that should not be imported

We currently have console warnings in the script for things like missing lat/lng, missing stname, etc.

If a record has no lat/lng, it does not belong in the geocoder, and should be excluded from the output.

The end state we shoot for is a 1 to 1 match for records in the normalized pad CSV and records in the elasticsearch database. This will be helpful in troubleshooting the imports.
