Improve reading of netCDF files with degenerate dimensions
- Support the case of degenerate dimensions that are not used by the variables being read.
- Support degenerate dimensions that are being used by the variables regardless of the numerical position of the degenerate dimension. For example, if T is the degenerate dimension, support reading Y,X,T or T,Y,X.
Both changes are needed to support the reading of climatologies from the NMME climatology datasets published by NOAA.
