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.
