Pascal Langer 4a626eaf14 Change XN297 emulation layer
Loads of protocols have been touched by this change. Some testing has been done but please test on all your models.
The XN297 emulation selects in this order:
 - the CC2500 if it is available and bitrate=250K. Configure the option field automatically for RF tune.
 - the NRF for all bitrates if it is available
 - if NRF is not available and bitrate=1M then an invalid protocol is sent automatically to the radio.
CC2500 @250K can now receive normal and enhanced payloads.
OMP protocol supports telemetry on CC2500 and is also for NRF only modules including telemetry.
Separation of E016H (new protocol) from E01X due to different structure.
MJXQ, MT99XX, Q303 and XK: some sub protocols available on CC2500 only.
