EFA(3pm): document non-dm constructor args

Travel::Status::DE::EFA is an unofficial interface to EFA-based departure

monitors.

It reports all upcoming tram/bus/train departures at a given place.

It can serve as a departure monitor, request details about a specific

trip/journey, and look up public transport stops by name or geolocation.

The operating mode depends on its constructor arguments.
