The optional "-m <multi.dat>" command line option can now be used to
specify a data file that can include multiple management frames with
each one prefixed with a 16-bit big endian length field. This allows a
single fuzzer run to be used to go through multi-frame exchanges. The
multi.dat file shows an example of this with Probe Request frame,
Authentication frame, Association Request frame, and an Action frame.
