r.resamp.stats always generates DCELL output.

In theory, the same logic could be used for anything which uses
lib/stats, i.e. r.neighbors, r.resamp.stats, r.series,
r.series.interp, r3.neighbors, and v.vect.stats.

Some of those only use the unweighted methods, in which case the logic
would be simpler.

v.vect.stats has the output type dictated by the type of the output
column. However, each method has a flag to indicate whether conversion
to integer should use truncation or rounding. Rounding is used for
methods which can return non-integer results for integer data.
