Built in special bytes that will need to be encoded in the binary packet format. This is not an exhaustive list, as other bytes such as ublox and rtcm preambles will be encoded as well, but these messages are not parsed and handled in the com manager, rather they are forwarded via the pass through handler. A byte is encoded by writing a 0xFD byte (encoded byte marker), followed by the encoded byte, which is created by inverting all the bits of the original byte. These bytes are not encoded when written in the proper spot in the packet (i.e. when writing the first byte for a binary packet, the 0xFF byte, no encoding is performed).
