Review Comment:
`Schema` exposes an `addProp` method. We could try to add a prop here that
allows us to determine that a fixed byte array should be treated as an UUID in
XTable

Review Comment:
technically there is a logical type for UUID in recent versions of avro
https://avro.apache.org/docs/1.10.0/spec.html#UUID, but this is mentioning it
is really just an annotation on a string field.
