  1. Delete unused serde_derive #[macro_use] 

    In old versions of rustc (1.15 through 1.29) it would cause a warning if
this #[macro_use] was not present.

    warning: proc macro crates and `#[no_link]` crates have no effect without `#[macro_use]`
       --> serde/src/lib.rs:340:1
        |
    340 | extern crate serde_derive;
        | ^^^^^^^^^^^^^^^^^^^^^^^^^^

These days serde_derive requires a newer compiler than that, so the
bogus warning would never occur.
