Wrap thresholding filters derived from itk::HistogramThresholdImageFilter

See the inheritance diagram here:

https://itk.org/Doxygen/html/classitk_1_1HistogramThresholdImageFilter.html

Start with the ITK HistogramThresholdImageFilter inheritance diagram linked in the issue and inspect the repository for existing filter wrappers. Identify the derived thresholding filters that belong in the plugin; done means those filters are wrapped and available consistently with the repository's existing image-processing components.
