* @brief Add support for CRC32
*
* Disabling CRC32 will reduce program size (for small micros).
* If CRC32 is disabled, XOR will be used as the preferred checksum
* method.
*
* Received CRC32'd messages will be accepted without checking.
*
* If handshake is used, the peer will detect that CRC32 is not
* supported here, and should start using XOR.
