[pdal] looping multiple bounding coordinates in PDAL Pipeline

[Nicolas Cadieux]

Ok, 

Running the command in a python script will be the next step in my opinion. This will permit the looping process.   Do you need to multithread the task to make it faster?  I will try to  look at this tomorrow.  I have some examples I can give you that will help.  

I am not a pdal guru but if you figured out the command, the rest is probably easy in Python.  Others, please help out if you have better ideas.

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].
