b6740eb437 Experimental tweak to FT8 decoder. Try a second symbol metric if the first one fails - currently configured to use max-amplitude and max-log.

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).

73df0d00ef 1. Alt+F8 arms "Call 1st" as if a CQ had been sent.
2. "Call 1st" label turns red when armed to respond to a caller.
3. Suppress some recognizable false decodes, send them to cumulative file
   "data_dir/false_decodes.txt".
4. Reduce sleep delay in decoder() to 10 ms.
