[Feature Request]:Deadzone configuration

[Waffl3Hunt3r]

Description

An option to adjust the deadzone for tilt controls and IR pointer in the Controller map menu.

Reason

Originally wanted to add a 10% deadzone since the emulated wiimote picks up on my controller's very minor stick drift. I also think the feature would be greatly appreciated for anyone with finicky sticks.

Examples

Dolphin for desktop has an option to adjust deadzone configurations for IR & tilt input.
