[FEAT] Adding a GUI or TUI

[Jarro01X]

Hi!

I recently saw that there were plans to add a GUI at some point. I can for sure take care of that, but I think maybe a python TUI framework, like Textual, would be better.

Let me know what you all think and I can start working on it!

Update from PR #243: PR#243 adds USAGE.md with GUI instructions covering both Streamlit (theZoo_streamlit.py) and Tkinter (theZoo_gui.py). The Streamlit UI from PR#236 is now also documented with startup instructions.
