Transformer class abstract

Transformer allows changes to the request/response data before it is sent/received to/from the server.

Dio has already implemented a BackgroundTransformer, and as the default Transformer. If you want to custom the transformation of request/response data, you can provide a Transformer by your self, and replace the BackgroundTransformer by setting the Dio.Transformer.
