In order to reference UserDefinedType we have to change the package name.

My use case for this is serializing Enum[_] types. I'm doing this as strings on the backend. However, in my tests it was still presenting the native enum type to the native avro reader. By moving the StringType out and explicitly calling .toString on it I'm able to get around this issue assuming the UserDefinedType for my enums is StringType.

As outlined in #235 it is desirable to get Avro serialization working with
UserDefinedTypes. This PR addresses that concern and allows serialization ofUserDefinedTypes. I wasn't able to write any tests, but I'm sure that can be done easily. This works on my local projects.
