Subject: [PATCH] Reduce CRKBD firmware size by reducing layer numbers (#5471)

* Reduce CRKBD firmware size by reducing layer numbers

* Update layer output code based on mtei's suggestion/code

* Fix spacing

* Revert "Update layer output code based on mtei's suggestion/code"

This reverts commit 036d347db309170afd5676e694adfda69f912615.

Unfortunately, because this is NOT in the keymap itself, the layer macros aren't accessible and will error on commit

* Add comment for future person
