Add hash computation to DCCL codecs based on the parts of the Protobuf descriptor that actually affect DCCL encoding. Added unit test and new codec "dccl.hash" that will send an arbitrary sized (in whole bits) portion of the std::size_t hash and check it upon receipt. This allows the user to check whether the DCCL definitions have changed between the sender and receiver (at the cost of some bits). Fixes #125
