Derives the CRC_EXTRA seed of a message from its definition.
This is what makes a dialect this build has never seen usable: given a
message's name and its base fields in wire order, the seed comes out the same
as the one the dialect publishes, and a frame carrying that message then
checks like any other. Extension fields are excluded from the seed and must
not be listed.
