Support for COIN-M user data stream

[skliarovartem]

Trying to connect to futures websockets:

const ws = new WebsocketClient({
                        api_key: wallet.apiKey,
                        api_secret: wallet.apiSecret,
                        beautify: true,
                        baseUrl: 'https://fapi.binance.com',
                        wsUrl: 'wss://fstream.binance.com',
                    });

And getting error: { wsKey: 'spot_userData', error: "Unexpected '<'" }

You shouldn't need to override the urls. The WS client handles this for you. Here's an example for USD Futures: https://github.com/tiagosiebler/awesome-crypto-examples/blob/master/src/exchanges/binance/account-events/futures-balance-update.ts#L20-L68

As I understand subscribeUsdFuturesUserDataStream works for USDT-M. Is it possible also to subscribe to COIN-M? Many thanks!

Hmm unfortunately I haven't implemented COIN-M yet... https://github.com/tiagosiebler/binance/blob/master/src/websocket-client.ts#L1845-L1869

It should be relatively straight forward by adapting what subscribeUsdFuturesUserDataStream() does into what the docs say for COIN-M

Ok, I have created a fork and implemented there subscribeCoinFuturesUserDataStream of course rest client is empty right now, I use direct requests...

Cool, will you be making a pull request or would you prefer me to do it? Yes, the rest client for coinm is still a bit empty, it was only recently started by another user, but we can start adding methods to it for any needed endpoints.

ok, I will make pr, but next week
