[pdal] Splitting COPC file into fixed-size tiles

[Aurélien Bertron]

Hello Andrew,

If I don't set the origin, I get multiple PointViews as expected. My 
question was about setting the origin outside the bounding box of my 
points. In that case I only get one PointView. Am I wrong to expect the 
points to be splitted in multiple PointViews of size 5000m starting at 
the origin I set?

Regards,
