enable scrollbar support in highcharts (already in highstock)
scrollbar support is available in highstock, but not in highcharts. it does not merit a license for highstock just for scrollbar functionality.

Scrollbars are available for any axis, but you need to load the Highstock library: https://www.highcharts.com/blog/news/224-scrollbars-for-any-axis/
We can load highstock without the license for highstock? We don't want to get the license for it just for the scroll bar.
