MPAS Version 8.2.2

This bugfix release addresses several issues in the MPAS-Atmosphere model
and in the MPAS infrastructure. Specific changes include:

• Fix to a portability issue in the MPAS registry 'parse' tool, which caused
  files in the src/core_<CORE>/inc directory to not be generated correctly at
  build time on some systems (PR #1229).

• Addition of two fields, brtemp and cldmask, that are needed by MPAS-JEDI.
  Although not needed by stand-alone MPAS-Atmosphere, these fields are
  associated with the jedi_da package and therefore have no effect when
  MPAS-Atmosphere is run without setting config_jedi_da = true (PR #1232).

• Removal of a redundant query of the nCellsSolve dimension in the
  physics_run_init routine. The extra query had no impact on results, and its
  removal can be considered clean-up (PR #1236).
