Fairness and sendorder methods on HTTP/3 SendStream

[martinthomson]

@jesup added these, but clippy is very confident that the methods are not used:

    fn set_sendorder(&mut self, conn: &mut Connection, sendorder: Option<SendOrder>) -> Res<()>;
    fn set_fairness(&mut self, conn: &mut Connection, fairness: bool) -> Res<()>;

Can they be removed? Or do we really not need these?

[mxinden]

SendStream is a private trait. None of the trait method implementations are called within neqo-http3. Thus I assume they can be removed (#1668). Am I missing something?

Am I missing something?

That's my question as well :)
