Problem: UUIDs are not lexicographically sortable

[sjmackenzie]

Solution: consider swapping out the uuid data type for ulid instead (https://crates.io/crates/ulid)

Universally Unique Lexicographically Sortable Identifiers are very useful in many scenarios.

I did create a discussion #280 a while back for adding ULID support to cozo, but there hasn't been any activity there. Currently running my own fork of cozo with ulid datavalue support.
