// The idea is to take a stream of bytes that looks like this:
//
// < One Byte Length > < Field A Data >
// < One Byte Length > < Field B Data >
// < One Byte Length > < Field C Data >
// < Two byte CRC16CCITT >
//
// Max length of fields:
//   A: 31 bytes, B: 40 bytes, C: 64 bytes
//   Total (incl. metadata): 140 bytes
