Accel(?) 360 Steering Wheel action support

[Ryochan7]

It might be nice to add support for accel(?) 360 steering wheel support. DS4Windows relies on the DS4 accelerometer to keep track the angle of the DS4, interpret the input depending on the current DS4 position, and adjust the output accordingly. I mainly use the mode while playing Euro Truck Simulator or American Truck Simulator. If possible, it might be better to finally figure out a way to perform sensor fusion to create a fake quaternion to keep track of the orientation of the controller and use that to detect the current Yaw angle of the controller. Would need to double check but I believe that the Pitch would have to be tracked for a JoyCon when place sideways in a steering wheel shell.

No need to fake a quaternion with the Steam Controller. The controller provides that data in its input report. Been wanting to play some ATS lately especially with the release of the Illinois DLC; probably a better experience than driving in Illinois IRL. I really miss using DS4Windows for faking a steering wheel for playing driving games.
