Though something to point out that this project misses is that UUID sorting is its whole own weird can of worms. I just went through this exercise trying to get ULID to GUID conversion/round-tripping that matched MS SQL Server's GUID sort order in hopes for the benefits of those small, pleasant properties.

In short, because SQL Server's sort order is based on GUID/UUID v1, the "group" that matters most significantly for sort order (in SQL Server, but other GUID tools are different) is the tail 6 bytes (not the head bytes as these FUUIDs are using which would allow them to sort in unix sort in GUID form). (As the tail 6 bytes are the "machine ID" in v1 UUIDs.)

For anyone curious how deep (and which endian) the rabbit hole goes in GUID sorting, I kept referring to Raymond Chen's somewhat comprehensive description of GUID sort orders across Microsoft products in my efforts: https://devblogs.microsoft.com/oldnewthing/20190426-00/?p=10...
