[Keymap] sneakbox keymap and userspace code (redo) (qmk#10977)

* Add support for LAYOUT_alice to sneakbox pcb

* define variables for sneakbox led pins

* set rules for sneakbox pcb

* add rotary encoder to userspace

* fix rotary function

* add custom layer indicators for sneakbox

* Revert "Add support for LAYOUT_alice to sneakbox pcb"

This reverts commit 5ed94d8.

* add license header

* Use  KEYBOARD_sneakbox_aliceclone

* cleaned up indicator code
