Pass hints to fst240sim, genfst240, and packjt77::pack77 on WSPR msgs
...
Due to an ambiguity with message encodings between 77-bit QSO modes
and 50-bit beacon modes with message types 13.n3 4.0 and 0.6 a hint
needs to be passed to ensure the right encoding is emitted. The hint
only effects ambiguous messages, others will be encoded strictly
according to the message content.
