Parallel coordinates with response coloring

[asnyv]

Parallel coordinate plots are already included in several plugins, but none of them currently allows coloring by a response value. Could either be an optional extension of the current ParameterParallelCoordinates (though responses are currently not a part of this plugin), alternatively a view option in ParameterResponseCorrelation or a standalone plugin like ParameterResponseParallelCoordinates. Standalone might be the cleanest option in the long run?

It is technically already possible with TablePlotter from webviz-config, but think this could be so useful that it is worth a standardization. Would also make the possibility clearer for potential users.
