Clean up re-exports and make small improvements to documentation (#607)

* Create issue_handler.yml

* No longer re-export `embedded-hal`, hide exported macros in documentation

* Add simple package-level documentation for each HAL package

* Clean up/simplify re-exports

* Fix the examples that I broke

* Ensure top-level modules/types/functions have doc comments

* Update CHANGELOG

* Re-export the `soc::psram` module where available
