add a directory /jedi/interfaces/geos_atmosphere/observations/localization
each yaml in that directory is used to update localization for the corresponding observer

A quick question, did we confirm having localization in observation YAMLs break the Variational applications?

A quick question, did we confirm having localization in observation YAMLs break the Variational applications? @Dooruk, the added directory jedi/interfaces/geos_atmosphere/observations/localization is used by local ensemble da only. And other modifications are in
M       src/swell/tasks/run_jedi_local_ensemble_da_executable.py
M       src/swell/test/suite_tests/localensembleda-tier1.yaml
This PR does not affect variational runs.
