[Photon] Import only the region

[Hamminger, Maximilian]

The easiest and probably fastest way would be to only import the region
in the first place. For this, you could quickly spin up your own
nominatim instance and import just the UK. From this you could then
import the data to photon.

The UK as an extract is available for instance at geofabrik:
