\brief Some modules contain external RF switch controlled by two pins. This function gives RadioLib control over those two pins to automatically switch Rx and Tx state.
When using automatic RF switch control, DO NOT change the pin mode of rxEn or txEn from Arduino sketch!
\param rxEn RX enable pin.
\param txEn TX enable pin.
