Precip imported from Surface / Spack / CI changes
This is a zero-diff update; requires GEOSgcm_GridComp v1.15.2 or later.
New in this release:
- Modifications to receive Observed Precip data from Surface GridComp Exports (rather than an ad-hoc READ from within Chem). Therefore, Precip into Chem is based on whatever method is used in Surface.
- Moved CircleCI to use circleci-tools orb
- Updates to CMake to support Spack
