Port over plotRefSLDHelper from the MATLAB code

This issue is a feature request

Port over the plot function (utilities/plotting/plotRefSLDHelper.m) from the MATLAB. Prioritize speed when selecting a python plotting library. The plot should be arranged similar to the MATLAB version

In addition to any unit test, the plotting should be tested using the demo Pybind example by replacing the function fakePlot with the new plotRefSLDHelper function.
