Feature request: options for remote bombchu aiming

1. option to un-invert the steering; I find it really difficult to use as-is with left and right being backwards.
2. option to make the bombchu work like vanilla when shield dropped so the player can choose when to use the remote control, since it's useful for puzzles and the bowling minigame but makes the regular blowing up of rocks/grottos/enemies more cumbersome than the feature is worth imo.

No files or tests are named. Start by locating the remote bombchu aiming and shield-drop handling entry points, then inspect how existing gameplay options are defined and tested. Done means players can independently configure steering inversion and whether remote control activates after dropping the shield, without changing vanilla behavior when disabled.
