e232c32178 Use 3rd order polynomial fit to estimate the noise baseline. The 
polynomial fit is done over 400 Hz bandwidth for T/R periods longer
than 15s, and over approx. 600 Hz (10 times the signal bandwidth) for
T/R period of 15s.

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.
