P25 Audio Decoder - changed sync pattern matcher to allow up to 2 bit mismatches on audio message frames when in the middle of a call.

Encrypted audio is still going to the audio output -- have to add error detection and correction to the ldu link control messages before I can use the encryption flag as a valid sentinel value.

P25 audio work in progress - started work on exposing 88-bit (11-byte) IMBE voice frames from LDU messages. Added deinterleave, derandomize and the Golay(23,12,7) error detection and correction to LDU voice messages. Hamming edac still remains to be implemented. Plan to create a separate project to produce an imbe FormatConversionProvider that will convert 88-bit imbe frames to PCM audio that is then in a standard format for audio playback, recording, or conversion to another format like shoutcast.

P25 LSM work in progress. CQPSK demodulator is working now, but there is a slight phase error in the constellation (it's rotated right by 5-10 degrees). I'm not sure if this is an error coming from the decoder, or if it's reflecting a phase imbalance from the source tuner i/q data.

P25 LSM decoder work in progress. Adds a CQPSK decoder based on Max's (KA1RBI) scope.py and gardner loop.
...
The CQPSK decoder is starting to take shape, but needs more tweaking and testing. It's not keeping a good lock on strong P25 signals. I have to add some more features to the intrumentation package to allow me to visualize the internals of the CQPSK decoder so that I can get a better sense of what needs fine tuning.
The CQPSK decoder may work for anyone that wants to sync the repo and run the build script.
