Run the AMS-II.H emission reduction workflow

Chains the AMS-II.H equation helpers to convert decentralized baseline and centralized project monitoring data into net emission reductions. Baseline and project datasets describe fuel use, emission factors, and optional useful output alongside auxiliary electricity and leakage estimates.
