 - 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

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.
