New sunset_prov_downscale.R function to describe Downscaling provenance. Also fixed some bugs realted to sunset_prov_verification.R

New 'sunset_prov_verification.R' function to describe the Skill module operations. It's been developed within the METACLIP ontology framework, adapting the vocabularies to what's useful to us. Still, waiting for the extension to happen to adress the matter with more detail

Modified 'sunset_prov_indices' to add an aggregation node of hcst and obs before defining the IndexCalculation node

Added 'sunset_prov_indices' for index calculation provenance (tested it succesfully with NAO_recipe.yml)

Finished adjusting the Reggriding provenance and included a new provenance function for calibration 'SUNSET_PROVENANCE/sunset_prov_calibration.R'

Finished the Regridding provenance implementation inside 'sunset_prov_dataset.R' and organized the functions. 'metaclipR_SUNSET' folder to store metaclipR modified functions and 'SUNSET_PROVENANCE' to store direct provenance functions + other developed tools

New provenance test focusing on dataset and datasubset, adding the new function that trasforms s2dv_cube into climate4R object

New provenance testing using a new function that transforms s2dv_cube into climate4R objects! Could include metaclipR.Datasubset()

Same as last push, but added a common command node for the fcts/hcst and the reference/observation data

Merge branch 'dev-test-provenance' of https://earth.bsc.es/gitlab/es/auto-s2s into dev-test-provenance

Merge branch 'dev-test-provenance' of https://earth.bsc.es/gitlab/es/sunset into dev-test-provenance

Removed line to prevent an error (same that happened on GitLab CICD runner) and added some metaclipR calls in the test file
