Rework of REMIND climate assessment integration - Reporting

[tonnrueter]

Purpose of this PR

First part of the reworking the REMIND climate assessment integration. Affects climate reporting via MAGICC7_AR6.R

• Script has been consolidated using the remindClimateAssessment and piamenv packages

• Python environment handling is done by piamenv::condaInit and piamenv::condaRun

  • Move towards conda run-based Python integration. This alleviates interference between R and Python environments
  • Init commands allow fine grained control of conda env activation
  • Only drawback so far in the new implementation is that logs are not printed linewise but dumped all at once
  • TODO (in a later PR): Archive Python run environment
  • TODO (in a later PR): Adapt scripts/input/climate_assessment_*.R to piamenv/remindClimateAssessment usage

• remindClimateAssessment handles all aspects of setting up runs of IIASA's climate-assessment library

  • Features a configuration concept that absorbs the previously tedious file name record keeping. List climateAssessmentConfig contains all directories and file names relevant to set up a climate assessment run
  • Run time reporting for various parts of the script was implemented by storing run times in a named vector. reportRunTimes generates a report and attaches it to the log file
  • Write climate assessment parameters to gdx via remindClimateAssessment::dumpToGdx
  • Relies on config files to associate climate assessment variables. gdx filenames and REMIND/GAMS variables names
  • remindClimateAssessment::archiveClimateAssessmentData stores climate assessment data of a particular run in a tar archive

check.yaml fails with

remindClimateAssessment: Can't find package called remindClimateAssessment.

We need to add remindClimateAssessment to the PIAM CRAN
