Detailed Description

Byte-stream CRC block.

Input: stream of bytes, which form a packet. The first byte of the packet has a tag with key "length" and the value being the number of bytes in the packet.

Output: The same bytes as incoming, but trailing a CRC32 of the packet. The tag is re-set to the new length.
