Bernie Stone case study

[JohnCRuf]

This PR is downstream of PR #26. This PR also addresses issue #19.

It adds a new task that creates case-study maps of Bernie Stone's vote counts and total menu contributions. We find that quantitatively, the rumors are true. Bernie stone did not seem to spend much on the west side of the ward, where he loses most of the elections.

@tmalthouse try to give this a review over the weekend if possible. Just quickly go through it to make sure the readme's are accurate and the code runs.

Readme files look good—I'm having some trouble getting the code to run, but I'm fairly sure that's just a dependency problem in my R installation.

[JohnCRuf]

Oof, I may have forgotten to add the new packages to setup_environment. Run that and let me know of any packages that I forgot.

nvm—just figured it out. My docker install was fubar. Reinstalling now—hoping this'll fix it.

[tmalthouse]

Docker is fixed, I am now erroring out in data_scrape_elections. Attached is the output of that task's makefile—it seems that I'm getting an empty response. Could you try rerunning this task to see whether the problem's on my end (maybe the ARM-AMD64 mismatch?) or on chicagoelections.gov?

Agh, the data scraping code seems to go stale every few months. Let me make a quick PR that commits the election data, and add an issue that this is stale.

[JohnCRuf]

Ok I think I figured out the issue: https://stackoverflow.com/questions/76294801/remdropen-hangs-when-using-rselenium-and-docker

I accidentally deleted my election data (WHOOPS) but I think this fixes the docker hang on line 35 when I open the selenium session. I'll remake it, add the code to a new PR, and submit today.
