6e308f0018 More attempts to diagnose or fix the FT8 "hung decoder" issue. 
On the Fortran side:
 - For the nzhsym=41 activation, bail out if m_ihsym reaches 45
 - For the nzhsym=47 activation, bail out if m_ihsym reaches 48
 - Change the format and content of what's written to fort.71
 - Change msdelay from 10 to 1

In mainwindow.cpp:
 - change format and content of what's written to qDebug
 - always start FT8 decoder at m_ihsym = 41, 47, and 50

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.

f2266c3c54 1. subtractft8: on the last call to sqf, don't need to do the long FFT. 
2. mainwindow.cpp: based on the time when <DecodeFinished> is received, calculate
mswait to try to place the killFile time at 0.75*m_TRperiod.

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.
