Minimize the production impact

[boris-petrov]

Right now, the minified production code that ember-test-waiters puts in a build is around 3.4K. It would be nice to make this as low as possible.

👍 totally agree!

We could likely strip out the code in a prod build. Would this work?

[boris-petrov]

That's the best way definitely if possible.

Was just poking around hoping there was something I could use for dynamic imports that wouldn't have prod overhead, would love to see this
