Add commands and listeners to generate location data of files
- `ReverseGeoCoderService` download the necessary files and build the `KDTree`
- `UpdateReverseGeocodingFilesCommand` command to allow to manually create the needed reverse geocoding files
- `MediaLocationManager` to manager the location mappings
- `MapMediaToLocationCommand` command to manually trigger location data mapping. Useful for pre-existing pictures.
- `LocationManagerNodeEventListener` to react to node, user and share events.
- `MapMediaToLocationJob` to reduce the load in event listeners
