Kruse86/mMass ? reverse-engineered prompt

I want to get this old mMass mass spectrometry app running again and make it easy to use on a modern machine.

Please inspect the codebase, figure out the main workflow, and bring up a working desktop app that lets me load spectra, view and inspect peaks, and do the basic mass spec analysis this project was built for. If the original dependencies are too old, update what’s needed so it runs cleanly today, but keep the app behavior as close to the original as possible.

If you need to look up current docs or library changes online, go ahead. I’d also like a simple way to start it from the main script, and if there are obvious broken parts from the old Python 2 code, fix them rather than leaving them half working. Keep the original feel of the program, just make it usable and stable again.
