Add onBarSelected returning the TimeRangeClicked

[saguado69]

Hi, it would be nice to have the possibility to get the time range when a bar is clicked/selected. Right now the widget shows a ToolTip but this will allow the widget to interact with others.

Thanks in advance for any support on this.

Hi @saguado69, That's good idea! I'll implement it soon.
