EFS Plots

[trevorb1]

Closes #228

Changes proposed in this Pull Request

In this PR I add a notebook for better exploring EFS data. Templated out in in are all subsector plots for California, Texas and New England, resampled to weekly sums. (Good idea @ktehranchi on re-sampling; way easier to understand!)

A couple general thoughts looking at the high-electrification/rapid scenario are:

• A lot of load for residential is being burried in the "other" sub sector for all regions. Will probably be good to clarify what is actually in this load.
• Residential "clothes and dish washing/drying" for Texas and California have considerably higher jumps from 2030-2040-2050 compared to New England.
• Residential/Commercial Space Heating and Cooling for California and Texas dont change too much; but that may be fair if heating demand isnt very much in these regions currently. NE's space heating demand shows significant uptick for winter electrification, which def makes sense.
• Residential Water heating does not change for NE which is surprising.
• Commercial Water heating for NE seems to decrease a lot between 2018 and 2024. This is also a little surprising, but given the amount of load hidden in the "other" category, this may be due to other factors.
• There is a big jump in light-duty EV load between 2030 and 2040, which makes sense. However, there is an almost equally big jump (~80% the size) between 2040 and 2050 for all regions. I guess for hgih-electrification and rapid adoption, I would have expected the 2040-2050 jump to be lower. But may just be me reading into it.
• Commercial water heating in all regions for all years has a noticeable (and abrupt) dip in the middle months. Would be good to figure out whats causing this.

Closing this, as its gonna get wrapped into a load validation notebook in PR #321
