WSJT-X/lib/jt9a.f90
Joe Taylor 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
