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.
