Postprocessing update: add output variables related to peak intensity & savings and emission intensity & savings

[JieXiong9119]

Pull request overview

This PR is to implement and register multiple output variables related to peak load and emission data, regarding calculated intensity and savings (and percent savings), and write to comstockwide csv in the postprocessing workflow. Changes take place in

• calculation in postprocessing/comstockpostproc/comstock.py
• naming constant conversion in postprocessing/comstockpostproc/naming_mixin.py
• unit conversion in postprocessing/comstockpostproc/units_mixin.py
• register entries to be written in final output (comstock wide.csv) in postprocessing/comstockpostproc/resources/comstock_column_definitions.csv

Changes I did not make that might be relavent:

• weighted savings calculation for peak load and emissions
• previously existing function add_normalized_qoi_columns calculating for a few peak load variables remains untouched, due to unit scale difference (w/ft2 in existing function, but kw/ft2 in added function)

@JieXiong9119 for processing the 2024 Release 2 SDR dataset we are making changes on this branch: https://github.com/NREL/ComStock/tree/wenyi/euss_r3, so please change the target branch of this PR to point to that instead of main. I already added the 15 daily_average_electricity_ghg_emissions columns back to that branch. Also, adding 215 calculated columns to all the public files is too many because these variables are not likely to be used by most people, so we can keep them in the column_definitions.csv and keep the code which creates them, but change the export options to FALSE, FALSE so that they don't end up in the public dataset. If you want to run postprocessing separately yourself with them set to TRUE, FALSE that's fine.
