Detailed Description

insert "pre-modulated" preamble symbols before each payload.

 input 1: stream of vectors of gr_complex [fft_length]
          These are the modulated symbols of the payload.
 input 2: stream of char.  The LSB indicates whether the corresponding
          symbol on input 1 is the first symbol of the payload or not.
          It's a 1 if the corresponding symbol is the first symbol,
          otherwise 0.
 N.B., this implies that there must be at least 1 symbol in the payload.
 output 1: stream of vectors of gr_complex [fft_length]
           These include the preamble symbols and the payload symbols.
 output 2: stream of char.  The LSB indicates whether the corresponding
           symbol on input 1 is the first symbol of a packet (i.e., the
           first symbol of the preamble.)   It's a 1 if the corresponding
           symbol is the first symbol, otherwise 0.
