[pdal] crop inside and outside

[Oscar Martinez Rubi]

Hi,

I want to crop the points in a file that are inside a polygon (or 
bounding box) into a new file but also want to put the points outside in 
another file.

I guess i can do this with two runs of pdal pipeline (one with 
inside=true and other with false) but this means all the points are 
processed twice Is there a way to do it in a single run in a way that 
the input file does not need to be processed twice?

BTW, my end goal is to divide the file into parts according to a fixed 
grid so if someone knows a better way of achieving this let me know please.

Thanks a lot!

Regards,

Oscar
