prevent some types of spurious fault plots from being made.

- [x] do not mark omitted indices as part of other badness types
      when plotting bad value markers. the assumption is that omitted
      indices have been cleared in some way by a human.
- [x] make sure that outlier bounds are transferred from Plotters to
      any BadTimesZoomPlotters that they create via plot_properties
- [x] BadTimesZoomPlotter now takes its plot_properties kwarg and
      uses it to update the default plot_properties, making it
      safe to change only a few plot_properties via kwargs
