[pdal] Took long time to generate Geo-tiff file after Update to Pdal 2.1.0

[Andrew Bell]

I don't see any changes of note between 2.0 and 2.1. You should run some
sort of a profiler or debugger in order to determine the root cause of the
change.  Note that you may get better performance by providing the bounds
of the output raster.
