Improved double range slider used in the following components:
- VueUiQuickChart
- VueUiXy
- VueUiDonutEvolution
- VueUiCandlestick
The double range slider handles can't overlap anymore.
An additional config option was added to control the color of the selected portion of the slider track:
VueUiQuickChart: config.zoomHighlightColor: string; // default: "#4A4A4A"
VueUiXy: config.chart.zoom.highlightColor: string; // default: "#4A4A4A"
VueUiDonutEvolution: config.style.chart.zoom.highlightColor: string; // default: "#4A4A4A"
VueUiCandlestick: config.style.zoom.highlightColor: string; // default: "#4A4A4A"
