Related #646

This allows searching for a rekor entry by the signed envelope hash. E.g. if a user has provenance.intoto.jsonl, then currently we can't search for that provenance unless we take the hash of the payload or Subject.Digest's. This way cosign will also verify-blob the hard way by searching for the artifact file hash.

The hash is the same as the hash in the rekor entry:

"Body": {
    "IntotoObj": {
      "content": {
        "hash": {
          "algorithm": "sha256",
          "value": "d05ff19cea34cd451c0a3133dc44d933e706fa00a910192f28b8dbe43d373020"
        }
      },
