LocalGsmNlpBackend

UnifiedNlp location provider (local GSM database)
New in version 1.5.3
- Add ability to customize lacells URL (thanks to Micha LaQua)
- Request legacy external storage as a workaround for setting optional database path
https://f-droid.org/packages/com.google.android.gms backend that uses local GSM data to resolve user
location.

A facility in the setting menu allows you to create a database using data from
OpenCellId and/or Location Services CSV files. Alternatively, the on-phone database can
be generated in advance via the lacells-creator scripts that gather tower information from those two sources,
too.

This backend performs no network data. All data acquired by the phone stays on
the phone and no queries are made to a centralized AP location provider.
