Error on WC*S query with binary encoding and ISO temporal subsets

[Piero Campalani]

When setting the parameters for GDAL (RasQL encode), temporal subsets are not translated to numeric coordinates.
Temporal subsets can be either numerical or ISO timestamps
(see PetascopeTimeHandling).

Usually time is sliced out in a time-series coverage, so parameters for GDAL are generally spatial coordinates.

Encoding of spatio-temporal 2D sections should be properly allowed anyway.

A related ticket is #708: GDAL will put an empty CRS in case we set a spatio-temporal compounding.
