default AnalogActionState getAnalogActionState( String actionName ){
        return getAnalogActionState(actionName, null);
    }
Gets the current state of the action (abstract version of a button press).

This is called for analog style actions (most commonly joysticks, but button pressure can also be mapped in analog).

This method is commonly called when it's not important which hand the action is bound to (e.g. if the thumb stick
is controlling a third-person character in-game that could be bound to either left or right hand and that would
not matter).

If the handedness matters use {@link #getAnalogActionState(String, String)}

{@link #registerActionManifest} must have been called before using this method.

@param actionName The name of the action. E.g. /actions/main/in/openInventory
@return the DigitalActionState that has details on if the state has changed, what the state is etc.
