serde_yaml can't be used with serde-transcode

[Mingun]

serde-transcode requires instance of Serializer/Deserializer, but in serde_yaml they is private...

However, nevertheless it is possible, but it is unusual. Just instead of

let deserializer = ...;
let serializer   = ...;
serde_transcode::transcode(deserializer, serializer).expect("Transcode failed");

it is necessary to use

let deserializer = ...;
let tc = serde_transcode::Transcoder::new(deserializer);
serde_yaml::to_writer(io::stdout(), &tc).expect("Transcode failed");

It would be quite good to bring to have an opportunity to write everything in the one standard

Thanks! Exposing the Serializer and Deserializer type are tracked in #44. Closing as a duplicate of that issue.
