fre.cmor: a CMIP7 example, toward general CMIP7 compatibility

[ilaflott]

Describe your changes

• adds cmip7-cmor-tables as a git submodule, right next to cmip6-cmor-tables
• adds a CMIP7-flavored example to fre/tests/test_fre_cmor_cli.py
• remove xfail from tests that now pass (in an intended manner)
• adds a new example (imperfect) user-input configuration for CMIP7
• cmor_mixer is still backwards-compatible for CMIP6 cases as of this PR. for CMIP7 cases:
  • adds global GLOBAL_MIP_ERA to cmor_mixer to track which mip_era a cmorization call is for
  • adds ability to detect mip_era. if CMIP6, function as previous versions did
  • if CMIP7, remove (but track) the brand from variable name in table and move on as normal
  • if CMIP7 and multiple brands possible for one variable, track all brands
  • if CMIP7 and multiple possible brands, check requested dimensions against available dimensions in input file(s)

Looks good. There was one contradictory logging message is all.
