Bill Somerville 731fe53a1e
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).
