Create a repository so we can add it to Altstore Pal

Hello, the current iOS installation process is pretty convoluted. I think a better approach to the iOS ecosystem would be to create a repo in which the Spotube iOS app lives, this way it is as easy as installing Altstore PAL, add the Spotube repo within Altstore PAL and then just install the app from that repo. This makes all the process super simple and doesn't require to use any PC, plus there is no need to keep renovating the app for it to work, Altstore PAL already handles the process.
