Refactor TokenOptimizer: Separate configuration, optimizations, and UI logic into distinct modules

- Created `config.py` to hold default options and theme data.
- Implemented `optimizations.py` for text optimization functions.
- Developed `ui.py` to manage the user interface using Tkinter.
- Added functionality for various optimization techniques including comment removal, keyword shortening, and type hint removal.
- Enhanced UI with theme support and improved layout for input and output sections.
- Integrated footer links for GitHub and roadmap access.
