- Fixed a problem in RH_ASK where _rxInverted was not properly initialised. Reported by "gno.sun.sop".
- Added support for waitCAD() and isChannelActive() and setCADTimeout() to RHGeneric.
- Implementation of RH_RF95::isChannelActive() allows the RF95 module to support Channel Activity Detection (CAD). Based on code contributed by Bent Guldbjerg Christensen.
Implmentations of isChannelActive() plus documentation for other radio modules wil be welcomed.
