This allows to get/set the Z Index value for Spline, Scatter & Line charts

sorry it was overlooked for a while, PlotOptions classes are generated so we should fix this in the generator which is not publicly available, will keep open until proper fix is added

@echarlus after taking a bit deeper look at zIndex usage I noticed it only makes sense when plot options are set to a data series and not when added to a Configuration via addPlotOptions.
I think it would make more sense to add zIndex to AbstractSeries instead.
Would this cover your use case for zIndex? or is the some case I'm missing where it would be more convenient to have it in plot options?

Hi, sorry for the late reply. It indeed makes sense to set it on the PlotOptions since I need to set it for the whole Series. So your implementation makes sense and resolves my issue. Thanks !

Ok, I will close this PR in favor of the implementation in #571 adding zIndex to series type instead of plot options
