412_64 move to handwired (#5359)

* 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."
