[FEATURE]-UserInterface Extensions UnSetValue

[cdenig]

Is your feature request related to a problem? Please describe. Group Buttons widgets rely upon the UnsetValue command to release all buttons, otherwise the last-pressed button remains highlighted. Group Button widgets also highlight the last-pressed Button by default without feedback from macro logic or control systems. As a user, it would be useful to not see the last-pressed button highlighted at all times. It implies the backing logic is in a particular state and does not show if the backing logic state has changed.

"xCommand UserInterface Extensions Widget UnSetValue WidgetId: "mygroup""

Describe the solution you'd like Update UpdateWidget function so that if value argument is empty OR has a a pre-defined value, the UnSetValue command is sent instead of SetValue.

Describe alternatives you've considered Do not use Group Button widgets.

Here's how i'd fix that. In CiscoRoomOsCodec.cs

        public void UpdateWidget(string val) // "/blinds /open"
        {
            var arr_ = val.Split('/');
            string id_ = String.Empty;
            switch (arr_.Length)
            {
                case (2): // "/blinds"
                    id_ = arr_[1].Trim();
                    ClearWidget(id_);
                    break;
                case (3): // "/blinds /open"
                    id_ = arr_[1].Trim();
                    var val_ = arr_[2].Trim();
                    UpdateWidget<string>(id_, val_);
                    break;
            }
        }

        public void ClearWidget(string WidgetId)
        {
            var command = String.Format("xCommand UserInterface Extensions Widget UnSetValue WidgetId: \"{0}\"", WidgetId);
            Console.WriteLine(command);
        }

There is an active branch working on the same class so i'm not going to cause repo conflicts by adding this myself.
