A crate of useful macros used in gix primarily.
Note that within gix-* crates, monomorphization should never be used for convenience, but only for performance
reasons. And in the latter case, manual denomophization should be considered if the trait in questions isn't called
often enough or measurements indicate that &dyn Trait is increasing the runtime. Thus, gix-* crates should probably
by default prefer using &dyn unless measurements indicate otherwise.
