is_binary proof will fail if proof does not claim to be a Merkle proof of a binary tree compatible with the one defined in Context_binary.

Note: It is very important to systematically check this before calling the verify_proof exposed in the protocol, since this function does not discriminate between binary and 32-ary proofs.
