Run analysis for all jobs

[grahamimac]

@ajjitn I've updated the code to run for all job loss estimates in another branch, per a few separate requests we've received. The current plan is to integrate this into the main branch at some point, but to run these as separate branches for the next release, with you taking the main branch and me running the all-jobs branch. https://github.com/UrbanInstitute/covid-neighborhood-job-analysis/tree/all-jobs

Once you get time (likely next month) we'll review and integrate into the October release.
