fix: issue making it impossible to use stack references (#162)

Turns out putting the stack reference function in `index.ts` was a bad
idea. Now, when importing it, the full Pulumi instructions from that
project get included in the parent project as well. Really bad.

This splits it out in a separate file. Do you think it looks OK? Not
sure if this is how to do it.
