Upgrade Clipper library

Description

Currently we use v4.8.5 of the ClipperLib for some of the geoprocessing like Clip and Dissolve.
With large files Clipper is much faster then GEOS (GDAL/OGR).
Version 6.4.2 is now available at https://sourceforge.net/projects/polyclipping/files/

This might solve some problems I'm seeing now.
