Feature description

Switch the piped instance the player uses to fetch music.

Why do you want this feature?

Player started throwing an exception for me so I dumped logs and found out this app used the piped api and the specific instance it was calling (piped.kavin.rocks) threw an error on the site when trying to play a video. I searched for other instances that would work for me and there was one and it would be nice if I could use it with innertune without building the app myself. Thanks.
