Enforce C++ compiler for Cython and fix Python binding

- Standardized the C++ compiler across build environments by setting it in `setup.py`, ensuring consistent compilation of Cython extensions.
- Transitioned to using `setuptools.build_meta` as the build backend in `pyproject.toml` for enhanced package build processes.
- Modified the extension module path in `setup.py` to align with the new Python binding structure.
- Introduced Python property decorators to `PyLimeConfig` class in `limedriver.pyx` for getter methods, enhancing the Pythonic interface of the Cython module.
- Facilitated direct import of the binding in `__init__.py`, streamlining the usage of the `limedriver` package.
