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.

Changed NID error detection and correction (edac) to using Berlekemp Massey 63-bit block decoder for the BCH(63,16,11) code so that we can correct up to 11 bit errors in a NID (versus previous 2).
