Support uuid v7

[Jengro777]

Describe the feature

Efficient cursor-based pagination relies on lexicographical and chronological sorting support, which is not provided by older UUID versions.

Suggested solution
UUID v7 fills a big gap in the database space by addressing the need for the lexicographically and chronologically sortable identifiers. CUID and ULID are strong contenders, but they come with a significant adoption friction involved, due to not being UUID-compatible, and hence not qualifying as a drop-in replacement.

Implementing UUID v7 support on V level would have a huge impact for addressing this need and enabling the adoption of the new standard. Since it is storage-compatible with UUID v4, it could already be adopted in existing databases with very little changes.

UUID v7 was already published as an RFC, see https://www.rfc-editor.org/info/rfc9562, so it should be safe to implement it already.

There is an existing Rust implementation: https://crates.io/crates/uuid7 - it implements the published RFC, and can be used to provide support.

Use Case

rand.uuid_v7()

I recommend to take as referential the most advanced official implementation for PostgreSQL. This thing is awesome
