Consider adding a type-hint for `Uuid`

[vegardgs-ksat]

It is common to use lots of UUIDs to for different resources. It is among the only identifier I personally use where having compile-time enforced origin check would be really beneficial.

Consider adding a type-hint akin to #[string] for the Uuid type, with appropriate From<Uuid> implementations. That would greatly simplify converting into its microtype at places of origin.

If desirable, the uuid crate dependency can be locked behind a feature flag.
