Disable character rotation in 4:3 mode to avoid artifacting (#72)

 - Currently the method used to clip sprites to the 4:3 window doesn't work with rotation
 - As there are only 2 places across all the games where this issue happens, we just disable character rotation in those scenes rather than trying to fix it properly
 - This should only affect images from the `sprite` or `portrait` folder
