Initial project config and implement build process

Enhanced the .gitignore to filter out additional build artifacts and Python cache files, promoting a cleaner repository state. Introduced a basic project structure with a new pyproject.toml, defining metadata and build requirements for the 'limedriver' Python package. Also added a LICENSE file and a custom setup.py which automates the retrieval and build of 'limedriver' submodules, streamlining the set-up for development and ensuring consistent builds across environments. These changes lay the groundwork for further development and distribution of the project.
