Add Prettier and format code (#415)

* Add prettier and configs

* npm run format

* Fix tslint error

- Prettier broke lines but the // tslint:disable-next-line comments remains in
the old position. They should be before the applicable lines.

- Enforce `SwitchCase` indentation level of 1 to match prettier behavior.
