Introducing headers for lume bar and line charts

[govind-srinidhi]

Feature description

Similar to the way we've an option to configure node headers in alluvial, it would be good to have something similar for bar and line charts.

The consumer will be able to add the header at each bar/point in the respective chart.

Problem/motivation

From the screenshot we can notice that there is a brief description about the bar on top of every bar in the stacked bar chart. Having an option to configure the node header would be beneficial, as the consumer need not have to worry about the positioning of these node headers.

Its better to do this at the consumer side instead of providing support from Lume. If bar/line charts are rendered with 10-15 bars, it wouldn't be a normal case to provide bar header for each of them given that hardly anything can be fitted in that header.
