Prefetch other bundles

Hey, I have the following use case, that I can't seem to get to work with your plugin:

- I have Page A with bundle/chunk X and Y
- I want to add a `prefetch` link on Page A for bundle Z since I'm going to need that on Page B

I have tried just using bundle names in the prefetch array, but that just adds a text string 'Z'.

Is this possible?

Start by reading how the plugin handles the prefetch array and resolves bundle names. Confirm how bundles X, Y, and Z are represented in the generated HTML, then determine what behavior would make Z available from Page A for use on Page B. The issue names no files or tests, so the project entry points must be located first.
