canboot_main: rework the protocol
...
All commands are now framed, where the payload must
always be included within a frame. A 16-bit CRC is postfixed
to each frame for validation. The protocol is now as follows:
<16-bit header><8-bit command><8-bit payload length in words><payload><16-bit trailer><16-bit CRC>
