This reverts commit 2e27f32d.

Please look at the merge request description for a full explanation, since I know the vanilla team has been hashing this out and I don't want to add fuel to the fire without at least presenting a solid case.

This _really_ needs to be a UINT8 array instead of
all this bit-shifting nonsense that saves no space,
but at least this way reading the menu structs doesn't
make me want to die.

It's okay, I literally had to remove one line lmao.

"left_hints" is always 3, 4, or 5, so the signedness is irrelevant.
But with ERRORMODE set to 1 when compiling,
the compile would previously stop due to comparing INT32 to UINT32.

With more than 5 but less than 10 emblem hints,
only put half of the hints on each side of the hint menu,
instead of putting e.g. 5 on the left and 1 on the right.
