Subject: [PATCH] DiscIO: Adjust WIA/RVZ header size heuristic

The heuristic was not allocating enough space for Metroid: Other M,
at least when using the default settings. (This didn't break the
file, it just caused some headers to be placed at the end of the
file instead of at the start and wasted a few hundred kilobytes.)
