FEAT: Support firing event when Bindings Change

[AnEmortalKid]

I recently found this asset after making my own version,

With the onActionChange callback on the InputSystem: https://docs.unity3d.com/Packages/com.unity.inputsystem@1.6/manual/Actions.html#inputsystemonactionchange-callback

It is possible to detect when a binding changes (ex a key is rebound): https://docs.unity3d.com/Packages/com.unity.inputsystem@1.6/api/UnityEngine.InputSystem.InputActionChange.html?q=InputActionChange

And fire the OnActiveDeviceChanged event.

Thanks for the suggestion, I'll aim to get this added in an upcoming release
