Need to add the --raw flag to cast proof in order to easily parse a tightly packed account proof (otherwise a small bash script is needed).

Example:
cast proof vitalik.eth --flashbots --raw

Current output is json, would expect --raw flag to return bytes memory accountProof and bytes[] memory storageProofs. Though some separation may be nice.
