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.

56a58fe6ab Implement "matched filter on s3(64,63)" as the criterion for hinted
(aka experience-based) decoding.

4fea8ebd0c Optimizations of JT9 and JT65 decoders; change clock in timer routine.
Both decoders now have slightly better performance and faster
execution.  The rare "duplicate decodes" in JT9 were eliminated.
On Windows, at least, calls to f90 routine system_clock() do not
provide correct wall time increments.  Changed to using secnds()
instead.
