wip: v2 addon codemod

[knownasilya]

TODO: figure out what to do with index.js

Next steps:

• customize the rollup.config.js to suit your needs
• audit dependencies of both the new addon and test-app
• run yarn install
• run yarn run lint:fix in each workspace
• test your addon cd test-app; yarn test

Now stuck on global failure: Error: Attempted to resolve x-toggle, which was expected to be a component, but nothing was found. but I don't use x-toggle in that form anywhere. I tried {{x-toggle}} and {{component "x-toggle"}} in rules with no luck.

Ok, so cached polyfil was the culprit. Now to figure out how to conditionally import styles based on config? OR maybe just instructions on how the user manually imports styles.
