Player model: save stream ID (hash)

[Ivshti]

save the hash (or prefix of hash) of the last playing stream in the LibItem, in order to be able to identify it on another device as well

Should be implemented as a StreamsBucket, which should behave and be structured in a similar way as LibraryBucket.

We could also persist the entire stream object and not just a hash against which we match later.

Possible structure of the StreamsBucket could be:

#[serde_as]
#[derive(Serialize, Deserialize)]
struct StreamsBucket {
    pub uid: UID,
    #[serde_as(as = "Vec<(_, _)>")]
    pub items: HashMap<(String, String), (Url, Stream)>,
}

where the key is (item.id, video.id) and the value is (addon.transport_url, stream)

• last_modified could also be added so we do not persist too old streams
