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.
