Browse source 
* Add Dip Switches as a core feature

* Add documentation for Dip Switch feature

* Update Preonic Rev3 to use new feature and remove custom matrix

* Apply suggestions from code review

Co-Authored-By: noroadsleft <18669334+noroadsleft@users.noreply.github.com>

* Remove custom matrix line completely

Rather than just disabling it

Co-Authored-By: fauxpark <fauxpark@gmail.com>

* DIP changes

Co-Authored-By: fauxpark <fauxpark@gmail.com>

* Use better check for DIP Switch configuration

* Add to show features

* Add bitmask callback for dip switch

* Fix OLKB Boards dip switch config

* Update docs to include bitmask example

* Fix comments/documentation

Co-Authored-By: fauxpark <fauxpark@gmail.com>

* Fix issues with docs and use example from @tuzonghua

* Fix wording

Co-Authored-By: fauxpark <fauxpark@gmail.com>
