* Remove patches and just use git dependency for PACs instead
* Various `README.md` normalization/updates for simpler packages
* Update `README.md` for `esp-hal` and `esp-lp-hal`
* Update repo-level `README.md`
* Un-pin the `defmt` package's version for `esp-hal` and `esp-hal-smartled`
* Bump `esp-println` and `esp-backtrace` versions in the `examples` package
* Mention lack of MSRV guarantees when using `defmt` feature
* Extract the `esp-hal-smartled` package
This (finally) eliminates the `esp_hal_common::utils` module!
* Remove all references to the old `smartled` feature from CI
