Details attribute(s) for address sensor

[pnbruckner]

Nominatim provides "broken down" address details in the raw.address attribute. Optionally add a sensor attribute, or attributes, that contain some or all of this information.

E.g., let user specify a list of details desired, and then if any of those exist in raw.address, add those as one or more attributes to the sensor entity.
