can cache medias and open it in Jellyfin-android

[nanqiangyipo]

1. In jellyfin, I can see which resources have local cache
2. Jellyfin gives priority to local cached resources when playing

After downloading, it cannot be played with jellyfin and don't know what multimedia is cached in jellyfin.When watching a 20 episode self-study tutorial, I hope to see which videos or audio have been cached, and jellyfin can give priority to playing with locally cached resources
