l1ctl_proto.h: define burst indication messages
One burst indication message carries a single raw burst, forwarded
to the higher layers from DSP. The burst bits are hard-bits (0 or 1)
coming from demodulator, packed to 14.5 bytes. This is why we call
them 'raw' - no bit correction nor deciphering is performed.
