Add rotation lock for Warioware Twisted

[correii]

First off, big thank you for making this game work with actual tilt controls. It’s amazing being able to play this game as originally intended.

However, it’s super annoying that the screen keeps rotating between landscape and portrait while playing the game. If you could add a rotation lock, that would be much appreciated. Maybe a toggle in the pop-up menu with the save state buttons and stuff.

There is a global portrait orientation lock built into iOS, but it’s limited to just portrait mode and not landscape. IMO the game is best enjoyed in landscape.
