[Keyboard] Add Stand Aside keyboard (#5360)

* 412_64 move to handwired

412_64 and its second printing, Mark Zero Stand Aside, are now obsolesced by new hardware. As only two units exist in the wild not owned by me, I'm moving the definition to handwired.

* Mark 3 Stand Aside ready for production.

Uploading firmware, compiled and tested, for Mark 3 Stand Aside. The hardware's ready, now the software is too.

* Whoops.

Should've branched before pushing Stand Aside. Sorry 'bout that.

* Revert "Whoops."

This reverts commit d222046cfe6183ed0c42286ec9ebb5034a5d1009.

* Revert "Mark 3 Stand Aside ready for production."

This reverts commit c790899af7a6d92855aebe6a96003f1fe9be66b3.

* Mark 3 Stand Aside ready.

Initial commit for Mark 3 Stand Aside, ready for production.

* Update keyboards/standaside/rules.mk

noroadsleft suggested removal of a line, 'LAYOUTS = ortho_4x16'. I agree.

* Cleanup for pull request.

Making changes requested by Drashna, as they're all good, and I know way less about the standards than they do.

* Initial cleanup completion.

Missed a few lines in standaside.c, they're cleaned up now.
