Stream::connect() never fails nor times out

[andrewdavidmackenzie]

Is your feature request related to a problem?
When I call Stream::connect() to connect to a known BLE device, if it is powered down, or absent, or connected to another computer/mobile, the attempt to connect never fails nor times out and my app is blocked waiting to connect

    let ble_stream = utils::stream::build_ble_stream::<BleId>(
        BleId::from_mac_address(&mac_address.to_string()).unwrap(),
        Duration::from_secs(4),
    )
    .await?;
    let stream_api = StreamApi::new();
    let (packet_receiver, stream_api) = stream_api.connect(ble_stream).await;

Describe the solution you’d like
A configurable timeout period on the connect method, which returns Result, and a specific error returned to show the connection attempt timed out.

If you do not wish to modify signatures, then adding a try_connect() methods that can timeout would be fine.
