Upgrade dependencies and de-lint (#87)

## Why are we doing this?
I was hoping to upgrade dependencies while doing #86, but the changes grew too large to combine with a feature so this is just a de-linting PR.

This upgrades to the pre-release 1.0 version of the org's Eslint config, which is much more closely aligned with the open source Airbnb config. Thus making progress towards #12 

## Did you document your work?

## How can someone test these changes?

Steps to manually verify the change:

1. `npm i`
2. `npm t`

## What possible risks or adverse effects are there?

none

## What are the follow-up tasks?

none
