Much easier to read. Optionals no longer store the 3-byte header in their memory reference. If they were smart, they could track per-game visitation date/time in a future header format... Fixes adding new side-formats and an updated header not writing the first time. Fixes GameDataPK8.CopyTo where PokeJob data copies from the wrong segment
