Once is done and we have parameterized the signature/hash alg used to sign deploys,
1. Add the ability to use the Ethereum way to sign messages called `ethsig`
It would work just as `ES256K` except that the hash all would use `eth_hash` as follows:
eth_hash = keccak256("\x19Ethereum Signed Message:\n" + len(message) + message))
Allowing for deploys to signed this way would mean we could leverage all the wallet tools that have been built for Ethereum (such as Metamask) to sign RChain deploys.
