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.

1. subtractft8: on the last call to sqf, don't need to do the long FFT.

mswait to try to place the killFile time at 0.75*m_TRperiod.

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.
