## Description
This PR removes simple prefix from all types in the crypto/merkle directory.
The two proto types `Proof` & `ProofOp` have been moved to the `proto/crypto/merkle` directory.
proto messge `Proof` was renamed to `ProofOps` and `SimpleProof` message to `Proof`.
Closes: #2755
- regenerate proto using docker image
- on proto breakage a different compiler is used to generate some more helper functions, on master the same one os not used, reverting back to the one used on master to undo further confusion till proto-breakage is merged
