Decompile progress art

[ghost]

Other projects like BFBB Decompile have a neat visual progress tracker to show the state of the decompile. This could be appealing to potential future contributors.

The closest thing we have is the build.py final output, which looks like this:

It would be nice to show similar progress statistics on this repository.

@riidefi You probably have a vision already for how this should look.

An external page might be overkill and I don't think it would get a lot of visitors. I could throw together a small script that generates a PNG file with some visual info (like a hilbert map and BR/VR MKW-themed art). That script can be hosted easily on Google Cloud Functions or App Engine as a web service that returns this PNG. This would allow us to embed it right on the repository README and keep it automatically updated.
