add helix keymap

that scene in phantom menace when they make it legal

try some led stuff

steal some functionality

revert some stuff

revert keymap;

revert display changes

add scripts and stuff

remove less-standard keybind

remove rgb since its brokenish

sync with new keymap

fix some config

maybe this fixes rgb

fix config

move to 4 row folder
