feat(pm): VFR registration callsigns and pronunciation (#28)

Browse Source 
- VFR scenarios get a German D-registration (e.g. D-EKLM) and its
  abbreviated form (callsign_short, D-EKLM -> D-LM) instead of the airline
  callsign; the pilot's first call uses the full registration, ATC uses the
  short form thereafter.
- radioSpeech: spell aircraft registrations phonetically for TTS
  ("D-EKLM" -> "Delta Echo Kilo Lima Mike", "D-LM" -> "Delta Lima Mike").
