4d5331899b When using click-to-decode in FT8 (nagain=.true.), the regular noise baseline estimator fails, producing erroneous and very large SNR estimates. Revert to the older signal-to-noise-plus-interference calculation for click-to-decode.

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).

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.
