Extend .gitignore and update build setup for C++ integration

The .gitignore file now ignores C++ build artifacts alongside existing ones. In setup.py, the build configuration for 'limedriver' was modified to include a new C++ source file, indicating a shift to or expansion of C++ code usage within the project. This change prepares the build process to handle and compile C++ code, potentially for performance improvements or new functionality that leverages C++ capabilities.
