Include version number in manifest

Was looking at your current output which looks like ```json { "files": { "example1.png": { "hash": "70740a80c43a42beecc70b4e9e1e8f2e25272e1e5fc15f691266848e9359403f", "size": 28778 }, "example2.png": { "hash": "cee5298da94a413da7e5e718a9c36c02feefe42904bac13f819b7021f8612f1d", "size": 14256 }, "example3.png": { "hash": "75f20a9723d5597404e9ffac44f8e26429f3a125898e6a4b9ea4c80aff9a1b28", "size": 27745 } } } ``` While I'm not expecting a manifest to be infinitely extensible, maybe you want to make it so you can evolve the hash? So perhaps you would prefer this manifest format instead? ```json { "version": 1, "defaults": { "hash": "blake3" }, "files": { "example1.png": { "hash": "70740a80c43a42beecc70b4e9e1e8f2e25272e1e5fc15f691266848e9359403f", "size": 28778 }, "example2.png": { "hash": { "blake3": "cee5298da94a413da7e5e718a9c36c02feefe42904bac13f819b7021f8612f1d", "sha256": "8d969eef6ecad3c29a3a629280e686cf" }, "size": 14256 } } } ``` Plus versioning would help in maintenance. Is there a file format documentation, perhaps you may also want this format to include description, timestamp, etc...
