Bill Somerville cccb38dbef
Pass hints to fst240sim, genfst240, and packjt77::pack77 on WSPR msgs 
Due to  an ambiguity with  message encodings between 77-bit  QSO modes
and 50-bit  beacon modes with message  types 13.n3 4.0 and  0.6 a hint
needs to be  passed to ensure the right encoding  is emitted. The hint
only  effects  ambiguous messages,  others  will  be encoded  strictly
according to the message content.
