If we want to have more semantically meaningful types (like Direction), it's useful to be able to support those in the DataSerializer too. Swapping bytes for entire structures is probably never going to make sense, but for types that are pure wrappers around integer types, we want to be able to swap them as if they were the integer they wrap.
