#2932: z values read instead of intensity in r.in.lidar

Comment (by dnewcomb):
I think in this case the value of the increased functionality justifies
the increase in complexity. It was my (mistaken) understanding that you
could use the base raster and Z values to filter for the points you want
to analyse , then depending on whether the -i flag was set or not you
either the run the statistics on the Z values or run the statistics on the
intensity values.
This would allow you to look at the mean intensities of the points within
half a meter above and below the base raster surface or get the mean
intensities of the top 3 meters of the canopy. One could even acquire
intensity statistics in 2m horizontal sections of the canopy.
My apologies in not communicating properly
