Fix the Snakemake plotting script

[samgdotson]

Currently the snakemake executes

rule make_plots:
    input:
        expand(r"data_files/{db}_{scenario}_model/{scenario}_OutputLog.log",
               zip,
               db=DBS, scenario=SCENARIOS)
    output:
        "figures/{scenario}_{sector}_capacity.png",
        "figures/{scenario}_{sector}_generation.png",
        "figures/{scenario}_{sector}_emissions_co2eq.png",
        "figures/{scenario}_{sector}_emissions_spent-fuel.png",
        "figures/{scenario}_{sector}_emissions_ewaste.png"
    script:
        "data_parser.py"

data_parser.py makes all plots by itself. This works but it's much slower than it needs to be because it makes ALL the plots for EACH input file. So much of the work is repeated numerous times. A single scenario run takes ~40 seconds to make all of the plots. With 5 scenarios in total, snakemake should take ~3.5 minutes. Instead it takes ~13 minutes (because it is repeating work).

This issue can be closed when...

When a new script has been added to snakemake that produces plots for a single Temoa output file to remove this repetition of work.
