Slowdown related to gamepad rumble

[kylekyleton]

v0.1.0-dev

Describe the bug
Game slows to a crawl while gamepad rumble is happening. As far as I know, the first time the game uses rumble is during the cutscene in which Kashiwagi appears at the first Impact battle -- and then during various events throughout the battle: punching, destroying missiles, using the chain pipe, etc.
Setting rumble strength to 0% completely resolves the issue.

To Reproduce
Steps to reproduce the behavior:

1. Play the game normally with rumble enabled during Impact battle

Expected behavior
No slowdown.

Might be related to this. Wiseguy mentioned that he will probably refactor the controller handling to be single threaded (move it to the main thread).
