Draft: plot_stackedbar; add a script that allow to build plot and his table

Link to #5101

What is done for the moment:

• Convert log string into structured data
• new component to generate a simple single stacked bar plot (d3js) and also generate a table of associated data (customizable)
• Use them to display a graph of proportion of each segmentation/unseg and locus proportion, showed in sample infopoint

Customisation of generated tooltip, value to refer for proportion, render table or not, ...

I tried to use it to generate new block in report menu but it seem to be more complicated that expected.
