* Improve dumping menu, add metadata dumping
* Use `NONE` as fallback DS save instead of `UNK`
Matches GM9 for my DSTT and バトル＆ゲット：ポケモンタイピングＤＳ
* Fix metadata check for NAND save
This doesn't seem to fully fix Face Training, but it might help?
Force push because I decided to undo disabling face training saves so it can still be tested
Technically this is actually more accurate, however it makes the dump not match a 'clean' dump (and there couldn't be a 'clean' dump like this as the save will always vary)
It now tries to dump, but the rest of the dump is garbage. It tries the save too, but I think that's also garbage.
This breaks some things that worked before, marked with TODOs. I'll fix them once NAND works.
