FT4: Imrovements to sync.
...
Divide DT search range into 3 segments. Search central segment (near DT=0)
first and try to decode the largest peak. Then find the largest peak in each
of the surrounding segments and try to decode those only if the peak is larger
than the one found in the central segment.
Also re-indent ft4_decode.f90 and some other minor tweaks.

FT4: Change Fortran code to NSPS=576 and make necessary accompanying
...
changes on the C++ side. Basically works except that Tx audio has
incorrect DT and audio is truncated at the end. Also, command line
decoding using JT9 is not as sensitive as decoding from within WSJT-X.
