Just use Prettier defaults

[jpdriver]

Some of the formatting in this project looks a little weird -- example

After I struggled to stage some new changes due to formatting issues, I think we should Just Use Prettier™️.

It seems to be the done thing nowadays.

• remove eslint-config-airbnb-base
• remove eslint-plugin-import
• add "plugin:prettier/recommended" to .eslintrc
• run Prettier

ps. as part of this we've switched from single to double quotes. If we feel especially strongly about including a specific override to stick with single quotes we can -- but my personal preference would be as few deviations as possible from the Prettier defaults

per comments below I've added a .prettierrc to retain enforcement of single quotes

No idea why I didn't use prettier from the get-go.. so thanks for this!
Could I be a pain and request single quotes? I know it's a personal preference thing but I feel like this is a fairly standard deviation from prettier's defaults.

sure thing. single it is!
