I don't think we do this directly, though it has been discussed.  You can
pass the geometries into filters.crop, but you need to pass WKT and then
use a writer that will write multiple views (LAS, BPF, OGR, GDAL).  If your
geometries don't overlap and overlap all points, you should get the same
number on output as on input.
