Logic to shift between the bars:
    KC_LSRE => Left Bar - Space... Right Bar - Enter
    KC_LERS => Left Bar - Enter... Right Bar - Space
    KC_LSRS => Left Bar - Space... Right Bar - Space

    Hack into dynamic_keymap_set_keycode and change the value of the keymap.
    (Just like VIA does, but instead it is done inside the keyboard so no need
    to open the app)

    Possible alternatives:
        - Create 3 layers but only change the KC_ENTER and KC_SPACE position between them
        - Create a custom keycode and use process_record_user to alter the behaviour
