[Feature Request] Support adjusting controls for games using SDL2 to handle controller input.

[supersmo]

I found a game that uses SDL2.dll for controller input and UEVR can't override the input.

Symptoms:

• I can't switch to HMD relative movement when using gamepad.
• Clicking both thumbsticks on gamepad or motion controllers does not open UEVR GUI and the GUI cannot be navigated.
• When using gamepad the game responds to gamepad input even when the UEVR GUI is open. ("Input pass through" not enabled.)
• I am unable to control the game with motion controllers.

Game tested: Laser League World Arena The game is no longer available for purchase and the servers are down but I'm still able to play the game offline with an old depot download from Steam. The game is a top down but it would be absolutely amazing to play in first person. HMD relative movement is the only thing needed to get it working in first person.

For now this may be a good thing for a plugin to support as they have full access to controller bindings but I'll leave this issue open

I've dug some more. I checked the logs and UEVR successfully hooks XInput according to: [UnrealVR] [info] [XInputHook] Done (1_4), so I'm not sure why UEVR can't intercept the XBox gamepad input or pass motion control input to the game.

The game has settings to use XInput or DirectInput and it is set to XInput. SteamInput is disabled in Steam.

I just saw the SDL2 dll among the game files so I assumed that it was the culprit but SDL2 should be using the XInput dll so I think the input interception should work.

Any ideas why it doesn't work?
