This removes the necessity to take the result of Response::into_json and having to convert it into a struct by using serde_json::from_value This adds no new dependencies since serde_json already depends on serde. Users of ureq will have to include `serde_derive` either by importing it directly or by using serde with the `derive` feature, unless they want to manually implement `Deserialize` on their structs.
