------------------------------------
Or maybe a 16-byte type, generally, not just for UUIDs.
> Add UUID logical type

> I think we should add a UUID logical type that is stored in a 16-byte fixed.
> The common string representation is 36 bytes instead of the 16 required.
> UUIDs are commonly used as unique identifiers, so it makes sense to have a
> good support. A binary representation will reduce memory when writing or
> building bloom filters and will reduce cycles needed to compare values.
