89434b0d97 Minor tweaks to JT65 decoding.

e25dd201a3 Experimental changes to JT65 decoder:
1. Change to rectangular FFT window for 2D sync spectrum (ss).
2. Move 2D sync spectrum array to common block.
3. Change to quarter-symbol steps for the ss array.
4. Allow up to 4 decoding passes.
5. Wire up Fast/Normal/Deep for 2, 3, or 4 decoding passes.
6. Make minsmo=0 (instead of 1) for minimally spread JT65B/C signals.

5afa11653a Back to original logic for decoding JT65A at HF, when "Single decode"
is not checked.

533bb81220 Various changes to JT65 decoding, all potentially temporary.
1. Measure Doppler width by fitting a (modified) Lorentzian.
2. Don't call "slope" in sync65().
3. New definition of "sync1".
4. Get snr from sync1.

2072f6f7c6 Look for weaker Sync indications when naggressive > 0 and ntol < 1000.

d7e7b43045 Many changes to the JT65 decode chain. This is development code! It
includes an initial implementation of the FTRSD decoder with a "qual"
parameter for evaluation of candidate codewords.  Also includes hinted
decoding.  Further testing is needed.

56e3638bc5 Increase the JT65 range of acceptable DT: now -2 to +5 s. Note that
displayed DT values appear to be to low by 0.2 s -- they range from
-2.2 s to +4.8 s, according to files generated by jt65sim.
