Implements decoding of FST4W messages as (240,50) crc-less codewords. 
By cascading the full 24-bit crc generator matrix with the (240,74) LDPC code generator, create a (240,50) generator that is used to decode with approximately 1 dB better sensitivity than the (240,64) with 14-bit CRC approach that is normally used. This approach treats the CRC bits as additional parity bits and provides no means for identifying incorrect codewords. All codewords on the list generated by the OSD algorithm have CRCs that match the CRC of the message payload. Codewords are validated by unpacking the message and comparing the unpacked message with the list of stored callsign/grid pairs stored in the fst4w_calls.txt file.

Reasonable default values for NB setting for command line jt9 
Use the -X command option to set  single decode mode and to set the NB
level.

    -X 256*(n+3)+s

Where s=32  selects single decode mode,  and 'n' is the  equivalent NB
setting as used in the WSJT-X UI.  Default for both is zero in FST4(W)
mode if no -X option is passed. E.g. -X 544 selects single decode with
NB=-1 (256*(-1+3)+32).

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.
