Calculate project agricultural emissions (Equation 2) — calculate_project_agricultural

Implements Equation (2) of AMS-II.F by converting monitored project fuel and electricity consumption into emissions. Inputs mirror [calculate_baseline_agricultural_emissions()] to streamline workflows. agricultural facility. in tCO2e per GJ. MWh. emission factors in tCO2e per MWh. tCO2e. Defaults to `"project_emissions_tco2e"`. grouping structure.
