* Fix changelog entry for MSRV change in axum-extra 0.3.5
* Bump MSRV to 1.60 for axum, axum-extra, axum-macros
* Use new Cargo features to avoid implicit features for optional dependencies
* Add `axum-extra` crate
Empty for now but now we have a place to put stuff.
I'll make a PR for moving over https://github.com/davidpdrsn/axum-resource.
* remove `authors` field from `Cargo.toml`s
