#3791: r.stats.zonal with -r option

-------------------------+-------------------------
 When using a -r option to produce a reclassified output raster as result,
 the r.reclass call at the end of the program could be *extremely*
 inefficient. I tried with large maps  many thousands of cats (derived by
 r.clump) and I got very long running times.

 Creating the rules files instead is very fast, even in those conditions.
 In many cases, it would be sufficient giving it as an (optional) output
 file and the r.reclass step could be avoided/postponed. BTW, undestanding
 why the r.reclass module could take ages would be nice, too.

 Cheers,

 Frankie
