[pdal] looping multiple bounding coordinates in PDAL Pipeline

[Jason McVay]

Examples would be extremely helpful! Multithreading would be ideal, but not essential.

I'm fairly comfortable with python and have set up pdal to work with my python environment, but haven't tried anything outside of the command line yet. I also have a csv with the following columns [minx, maxx, miny, maxy, id].
