Make Clutter From Measurement Plotter More Configurable

[mkierzenka]

It's neat how Plotter.plot_measurements() automatically handles plotting ClutterDetections as a different color/shape vs. TrueDetections (e.g. MTT_3D_Platform example below).

But when visualizing simulations that have a very high clutter-to-true detection ratio, a user may sometimes want to plot only the true detections without the clutter. Is there an easy way to do this? Perhaps it would be helpful to extend the Plotter.plot_measurements() function with an optional argument "show_clutter"?
