Before it gave expected result for points with Z, e.g. in full NC loc:

r.vect.stats in=elev_lid792_bepts out=ground

Now it gives error (likely due to column=options['column']), but more
importantly, other binning modules (r.in.lidar, r.in.xyz) have mean as
default, so we need to be careful not to be inconsistent and produce
expected results. Can this have no default? Or perhaps the "use" paradigm
as with other modules such as v.to.rast is appropriate here
(use=attr|cat|z), then again we have the issue of default value versus no
value for default, but at least it is general enough to accommodate both
XYZ point clouds and points with attributes.
