Changed `enable_lip` to `style_lip` to allow a choice between a regular lip, removal of the lip (losing 3.6mm of height) or remove lip while retaining the regular height
- renamed a bunch of stuff to make people's lives hard ig (more because the file hierarchy was really bad and needed improvement to make other dependent modules)
- updated README documentation to match new modules
- new constants file to clear up clutter in main files
- base function now separate from the bin function
