Add some optimization to the Tetris keyboard (#4645)

Fix up tap_code functionality (#4609)

* Add delay in Tap Code to avoid issues

I think a few people have reporting issues with it working properly, and it may be a timing issue.  The 'register_code' uses this sort of delay in some of the functions, and
this is probably why.

Adding the 100ms delay should hopefully fix any issues with it.

* Make tap_code delay configurable

* Update documentation

* Bring tap_code16 inline with changes

* Fix type for tap_code16

Bad copy-paste job

* Just use the value check for the define
