[SUGGESTION] - Break the python code apart

[altryne]

If we extract the "ui" part out of the webui.py script, and then use it with an import, then we can do a few things :

1. Develop UI faster - this would be possible as we could import the Gradio UI into a separate python file and run with debug=True (that's actually how I've been doing the dev, but it takes a long time to copy/paste back and forth)

2. Write stubs for all functions we use to load the ui dev faster

3. Merge syncs and PR reviews will be easier

This definitely needs doing
