savings percentage unit not percentage

just did a quick debugging of csv with @ChristopherCaradonna and found out

• this output var calc.percent_savings.electricity.cooling.energy_consumption..percent (from ComStock wide.csv) has a dimensionless unit rather than percent

• quick calc for one model shown below. 2nd col is baseline results and 3rd col is upgrade results.

• did not get a chance to check if other percent savings columns are experiencing the same thing.
