feat: initialize Flask proxy app with gitignore and license
- Added .gitignore to exclude virtual environment and Python cache files. - Included MIT License to allow use, distribution, and modification. - Implemented Flask app for proxying font requests to Google Fonts. - Ensured specific headers are handled correctly to support CSS proxying. - Added necessary dependencies in requirements.txt for Flask and requests. This setup allows for efficient font request handling and helps establish project structure with appropriate licensing and dependency management.
