Derive naming
What should we call the derive?
The implemented plumbing trait is FromPest. That's not what this discussion is about.
This is about the derive naming, which is currently #[derive(FromPest)].
This is nice, because it says what it does on the tin: it derives FromPest for the type.
But especially if we add a way to derive precedence climbing, it might make sense to split the derives into multiple.
Additionally, the current #[derive(FromPest)] is both in a separate crate from the trait FromPest (pest-ast and from-pest, respectively), as well as using #[pest_ast(..)] as its "attribute namespace" for additional information on the type and fields.
If PrecClimb gets its own derive (which I think could very well be beneficial both to internal code organization of the derive crate and the derive API), then I think the main derive should be renamed away from just the generic FromPest, as it doesn't cover all derive possibilities anymore.
