tooltip to target padding

[danielczykjakub]

Is your feature request related to a problem? Please describe.
Currently a distance between the tooltip and the target widget is hardcoded inside the package, with following constants:

1. _withArrowTooltipPadding = 16.0 when showArrow is true
2. _withOutArrowToolTipPadding = 10.0 when showArrow is false.

The code responsible for that logic is:

 if (!widget.showArrow) {
      paddingTop = _withOutArrowToolTipPadding;
      paddingBottom = _withOutArrowToolTipPadding;
    }

inside tooltip_widget.dart, line 463-466

and then:

padding: EdgeInsets.only(
                      top: paddingTop,
                      bottom: paddingBottom,
                    ),

inside tooltip_widget.dart, line 692-695

Describe the solution you'd like
It would be appropriate to expose this value as a configurable parameter, so that the vertical distance between the tooltip and the target widget can be changed.
