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.

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.

Joe Taylor 199ff3dd3d Experimental work-around for FT8 decoding on slow computers. Important changes: 
- don't start function decode() is decoder is already busy
  - send updated m_ihsym to jt9[.exe] via ss(1,1).  Bill won't like this!
  - jt9 bails out of the 41-buffer pass at m_ihsym=45.

Steven Franke 0ca6cbb575 wsprd: improve decoding and reduce the number of false decodes 
Hashtable entries now include the 4-digit grid obtained from the most
recent Fano decode of the callsign. The stored grid is used to validate
OSD decodes. OSD decodes of type 1 messages are accepted only if the
callsign is present in the hashtable and if the grid matches the grid
stored in the hashtable.
