Creates a Universally Unique Identifier (UUID) generated according to RFC 4122.

A call to UUID() returns a value conforming to UUID version 4, sometimes called
"random UUID", as described in RFC 4122.

A call to UUID(bytes) returns a value conforming to UUID.

The value is a 128-bit number represented as a string of five hexadecimal numbers,
_aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee_, for example, `237e9877-e79b-12d4-a765-321741963000`.
