Steve Franke 71cb6d9f50 Use 4 different Costas arrays to prevent false syncs as received frames move 
through the analysis window.

Add a random 77-bit vector to each message so that tone transitions occur
even if the message contains a long string of 0 or 1 (like a CQ).

Add alternative sync calculation as an option (sync2), for testing.

Add basic framework for AP decoding.
