websocket stream don't support extra config

[ramarro123]

it seems that

public Closeable onDepthEvent(String symbols, BinanceApiCallback<DepthEvent> callback) {
    String channel = (String)Arrays.stream(symbols.split(",")).map(String::trim).map((s) -> {
        return String.format("%s@depth", s);
    }).collect(Collectors.joining("/"));
    return this.createNewWebSocket(channel, new BinanceApiWebSocketListener(callback, DepthEvent.class));
}

don't allow to use the params specified here

https://github.com/binance/binance-spot-api-docs/blob/master/web-socket-streams.md#all-book-tickers-stream

for instance

Stream Names: symbol>@depth<levels OR symbol>@depth<**levels**@100ms

Update Speed: 1000ms or 100ms
