mHM netCDF output coordinate system:
- Due to lat and lon being stored as 2D array irrespective of iFlag_cordinate_sys, CDO and other operators read the mHM output as curvilinear/ projected even if it was otherwise.
- The lat lon are now stored as 1D vectors in case of lat lon system. This saves external postprocessing needed previously.
