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.
