[WIP] Add requirements.txt file with Python dependencies

[Copilot]

Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

Original prompt

Add a requirements.txt file to the repository with all the Python dependencies needed for the project.

Based on live.py, the following dependencies are required:

For the desktop app (live.py):

• PyQt6 - GUI framework
• opencv-python - Camera access and image processing
• numpy - Array operations
• ffmpeg-python - FFmpeg bindings for GIF conversion

For the FastAPI web app (to be added later):

• fastapi - Web framework
• uvicorn - ASGI server
• python-multipart - File upload support

Create a requirements.txt file in the root of the repository with these dependencies and appropriate version constraints for stability.
