Motivation

When creating structs with #[derive(FromQueryResult)] it is annoying to translate them into MockRow, because the type is not really supportive to any implementations. To achive that, the only way is to create a BTreeMap<&str, Value> which implements IntoMockRow.

Proposed Solutions

I think the best idea would be to drop the trait IntoMockRow as it is hard to implement from the outside and instead automatically implement From<R: FromQueryResult> for IntoMockRow however it might be necessary to do that through derive.
