Installing GStreamer Spotify plugin

To play spotify songs you need the GStreamer Spotify plugin from the gst-plugins-rs package, if you do not have it, you can build it from source this way.

   git clone https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs.git
   cd gst-plugins-rs
   cargo cbuild --release -p gst-plugin-spotify
   sudo cp ./target/x86_64-unknown-linux-gnu/release/libgstspotify.so /usr/lib64/gstreamer-1.0/
