Add the `SliderOption` option supporting:
```cpp
{
Ref<T> value;
ConstRef<T> min = T(0);
ConstRef<T> max = T(100);
ConstRef<T> increment = (max() - min()) / 20;
GaugeDirection direction = GaugeDirection::Right;
Color color_active = Color::White;
Color color_inactive = Color::GrayDark;
};
```
In particular, this supports multiple direction. This resolves:

This one do not support adding a label. The old constructors can still
be used to have a label.
