[jonbarrow]

Resolves #XXX

Changes:

Adds support for parsing ME01/SA01 archive files. This is required for Mii rendering in the future, since the Mii models mentioned in #2 are inside an SA01 archive

This is required for future Mii rendering

I think "SA01" = Sugar Archive?, which agrees with "sgarc" and other mentions of "sugar" as a codename.

The "ME01" part is really confusing, I'm seeing Switch Toolbox has this format (zero details on which game uses this, only mentioned one other time on the internet), but whoever wrote the parser noticed the two looked similar and also lumped the big-endian "SA01" into the same class, which is an.. interesting choice.
Only reason I'm looking deeper into this is because Mii Maker uses a custom-ish engine that I haven't seen shared between other games (And no sead, gsys, etc.) and I'm curious about "who" the developers were, or something.
