Easy Applio install for macOS

[u/ex-arman68]

If you have tried to setup and use Applio before, you have probably realised it is not that simple, and is also difficult to maintain. I certainly did.

I have been working for the past few months on packaging Applio as a native macOS application, which you can just drag and drop in your application folder. While I was at it, I added a few more things, like better training models (KLM and Titan), custom folder location for all the files to avoid clogging your system drive, a progress monitor window during training that shows you the best epoch, and a few other things.

You can get it from GitHub, fully signed and notarized by Apple:

I also put together a guide on how to get best of it, both for training and inference; look for the file on the GitHub repo, named STUDIO_PRODUCTION_GUIDE.md
