Add SolTab::GetSubArray() generalization

Bas van der Tolrequested to merge
ast-1657-extend-h5parmaterm into master

Reading idg-cal solutions is more performant when they are read in larger blocks. This MR further generalizes GetSubArray() to allow ranges for the axes antenna, polarization and direction.

The existing GetSubArray() now uses the generalized version for the actual reading.
