ADS-B Version returned even if no ADS-B message received #26

ModeSDecoder.getAdsbVersion returns 0 even if aircraft has never sent an ADS-B message.

This is not mentioned in the documentation. For clean semantics, the method should return null as long as no ADS-B message has been received by the aircraft.
