Hayley 18fba8f75d Decoded list fix 
Fixed the decoded list from growing exponentially, by moving the processSerial function to the decode function. This significantly reduced the audio delay. There still is a slight audio delay that gets output about a second after rekeying. For this fix, the processSerial function in the read thread was commented out and this casued a delay in receiving some of the control signals from the dongle.

Haylz 2d66da14a4 RX State Machine HEADER_PROCESSING to BIT_FRAME_SYNC 
The header processing stage always switched to the VOICE_FRAME stage. This caused garbage to be loaded into decode buffers. This fix changes the logic to only switche from HEADER_PROCESS stage to VOICE_FRAME stage if there is a P_FCS match, otherwise goes back to the BIT_FRAME_SYNC stage.
