[verb] `signature` - for comparing tables across regions or time 9 months ago

AI Summary: The issue proposes a new `signature` verb to generate a deterministic hash of a table or its parts, enabling efficient comparison of tables across regions or time without transferring large datasets. This would be useful for verifying data consistency or successful restores. A suggested implementation involves segmented scans, hashing each segment, and then hashing those hashes to pinpoint differences, requiring a robust, deterministic streaming hash algorithm.
