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
functions in the utility file should be more applicable to "extension" modules, so the baseplate generation was moved to its file. Removed some constants that should be defined by already existing constants. Altered the base generator function to make an accurate model instead of using a scale.
- 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
