Title: ENH: adding SimpleFilters as internal modules via externalproject

Following the example of MultiVolumeImporter, a new external project
was added to download the SimpleFilters repository, the source
directory is propagated into the Slicer project and it is added as a
sub-directory to the build in scripted modules.
