Expand description

An “extension trait” to add a the intern method to str, which effectively adds it to all types that directly or transitively implement Deref<Target = str>, which includes String, references, and smart pointers to str or String.

Ideally, I would like to ban Rc, but that would require auto traits or negative impls or something. My reasoning for this is that I suspect it will be a bit of a footgun, or at least an unintuitive behavior if Rc becomes an Arc when it gets interned.
