Introduced Sorting Algorithm Visualizer

- `displayer.py`: Handles the Pygame window, rendering, and visualization updates.
- `sound_manager.py`: Contains the `SoundManager` class for generating and playing audio feedback.
- `main.py`: The application entry point, setting up the initial visualization with a basic array.
- `algorithms/`: Directory structure for algorithms, starting with `bubble_sort.py`.
- Includes `requirements.txt` and a basic `README.md`.
