More work on FT2. New frame format is 16sync + 128codeword. Data chunk is assumed to be 2.5s long. A rudimentary sync routine is implemented which finds the single strongest signal.

unpack77 now returns logical variable unpk77_success, which will be .false. if there is something obviously wrong with the message. Still to do: set the flag if the unpacked message contains CQ in an implausible place.

No need to examine every entry in the hash table. Just calculate the hash of OSD-produced callsigns and see if they are in the table. Add OSD decoding to the deep setting for wspr decoding.
