[pdal] Raster extent with writers.gdal

[Jim Klassen]

There is also the /bounds/ option that lets you specify the output 
extent directly.

One thing you might have to check and adjust for is the output might be 
half a pixel off where you expect it to be (the difference between the 
geographical coordinate representing the center of the pixel or the corner).
