dd1362b69a Rationalize NA contest mode
Generic message packing and unpacking routines now understand antipode
grid contest messages.  These messages  are now recognized as standard
messages in  message response processing and  dealt with appropriately
when contest mode is selected and applicable (currently FT8 and MSK144
only).

d5d8abc29a 1. Improvements to the OSD to allow deeper wideband decoding. 2. Add a third decoding pass. 3. Change symbol metric from max-log to max-amplitude.

4a3cd7222f Improve efficiency of OSD by a factor of 5 to 10 for norder=2 and 3. Use norder=2 for wideband multi-decoding, norder=3 near nfqso and nftx.

9ae479e9d9 1. add error-pattern rejection to osd174 (factor of 3 speedup for norder=3)
2. osd codeword selected based on correlation discrepancy instead of Hamming dist (improves sensitivity)
3. trap zero-valued spectrum values caused by large dt.
4. trap all-zero codeword
4. both decoders return number of hard errors
5. osd174 returns correlation discrepancy (rejection threshold still needs to be tuned).
6. both decoders return the codeword with bits in as-transmitted order, for subtraction.
