Feature request: TDoA / multilateration support

[rkarikari]

Is it possible now (or in the near future) to geolocate a transmitter with SDRAngel?

It runs on gps enabled devices ( phones, tablets etc) and can use these for TDoA calculation.

multilateration should also be possible for modeS only planes to be plotted on the map.

This would be a great feature addition .
