Download button at the end of the build

Hi! first of all thank you for your awesome work!

I just used the patcher and worked nicely, but the computed I'm using is not the most powerful, so it took a lot of time to build.

However I have a big server that could do the job much faster. I could just run your app on it and access the interface remotely, but I still would need fetch the file from the server somehow. It would be great to be able to download the file directly from the web interface using a button.

That would also enable the community to have public instances of ReVanced builder

Thank you!
