perf(statusTile): faster array creation and lodash lazy loading

[haroldtreen]

Description

Reduces the activation time for prettier-atom from 248ms down to ~60ms.

Changes

• Removes the array spread operator from atomInterface. This stops babel-runtime from requiring large polyfills (babel-runtime/helpers/toConsumableArray). Saves ~70ms.
• Lazy loads lodash/fp/flow in editorInterface. This function is only used for getCurrentDir, but gets loaded whenever editorInterface is loaded anywhere. Save ~120ms.

LGTM, congrats on your first PR on the repo!

[robwise]

Maybe we will be able to revert this in a future PR if we implement babel-plugin-lodash? Or at least we can clean up a bit by implementing that import-lazy lib?

[haroldtreen]

Ya, I think there's a larger story to be tackled of "What's the pattern for lazy loading?".

This mirrors what's being used in main.js, but it can become a bit verbose.
Another PR for import-lazy would be interesting.

@haroldtreen Before I merge, can you rebase and then run nps build to update the dist files and amend the commit?

[haroldtreen]

Wooo! Thanks for the speedy response @robwise 🙌 !
