🩹 Remove unused use statement

Warnings are triggering on CI of an unused `use` statement in `astd`
caused by importing the `macros::*` module. This appears to be an issue
stemming from this module only containing macro definitions, which
technically only ever exist at root-level due to `#[macro_export]`.

This removes the `use` statement since it's effectively not needed.
