Coefficients missing on GetCoverage response when irregular axis not trimmed

[Piero Campalani]

Irregular axes are not showing the list of weighting coefficients when the axis itself is not selected for a trim subset (information of sliced axes is always dropped instead).

As an example, the following WCS request will properly show the coefficients along k (the irregular axis of our [RasdamanTestSuites test dataset] irr_cube_1) only when the second subset on k is added:

      service=WCS
     &version=2.0.1
     &request=GetCoverage
     &coverageId=irr_cube_1
     &subset=j(5,6)
+++  &subset=k(0,10)

This query represents the current workaround: adding subsets on the irregular dimensions which enclose all the points along it, will produce a correct response.
