feat: impl serde Serialize & Deserialize for Data enum & related structs

Also make it a feature if possible

created branch 13-feat-impl-serde-serialize-deserialize-for-data-enum-related-structs to address this issue

mentioned in merge request !8

I realized that it is currently only possible to implement Deserialize on the Data enum. This is because the types that Data holds are from an external crate and they don't implement the Serialize trait.

This won't be a problem if mquery takes over the de-serialization of the response. But for that, the external crate would have to expose an API that returns the raw response. This feature will remain blocked until that happens.
