Move CLI into paper-bin or new crate

[molikuner]

The crate paper is used as a swift package in BTLB. This app does not need the CLI functionality.

I fully agree. paper-bin was once a swift package, but we can very well re-use the name for the CLI.

Oh interesting. I wasn't aware of that. I would have thought the -bin comes from "binary" 😄. But yeah, it doesn't change the point 👍

It was called bin like 🚮
