Generic Set_PacketParams() command
Set_PacketParams(PbLength,PbDetLength,SynchWordLength,AddrComp,
PktType,PayloadLength,CrcType,Whitening) is used to configure the packet
handling for the sub-GHz radio. When the generic packet is selected with packet type in
Set_PacketType() sent prior to this function, the parameters are interpreted as below.
