UnsubscribeAsync stops all subscribers

[XHighIntell]

Describe the bug
When we have more than one subscribe to a one symbol. Unsubscribing one will stop all others.

To Reproduce

using Binance.Net;
using Binance.Net.Clients;
using Binance.Net.Objects.Models.Spot.Socket;
using CryptoExchange.Net.Authentication;
using Binance.Net.Enums;

static async Task Main(string[] args) {
    var client = new BinanceSocketClient(options => {
        options.Environment = BinanceEnvironment.Live;
    });
    
    var o = await client.SpotApi.ExchangeData.SubscribeToKlineUpdatesAsync("BTCTUSD", KlineInterval.OneMinute,
        x => {
            Console.WriteLine(x.Data.Data.OpenTime + " " + x.Data.Data.OpenPrice + " " + x.Data.Data.HighPrice + " " + x.Data.Data.LowPrice + " " + x.Data.Data.ClosePrice);
            if (x.Data.Data.Final == true) {
                Console.WriteLine("===========");
            }
        });
    var oo = await client.SpotApi.ExchangeData.SubscribeToKlineUpdatesAsync("BTCTUSD", KlineInterval.OneMinute,
        x => {
            Console.WriteLine(x.Data.Data.OpenTime + " " + x.Data.Data.OpenPrice + " " + x.Data.Data.HighPrice + " " + x.Data.Data.LowPrice + " " + x.Data.Data.ClosePrice);
            if (x.Data.Data.Final == true) {
                Console.WriteLine("===========");
            }
        });
    await client.UnsubscribeAsync(oo.Data.Id); // <--- Let unsubscribe one and keep another
    Console.WriteLine("Unsubscribe id=" + oo.Data.Id);
    Console.ReadLine();
}

Expected behavior
Should keep getting events.

Debug logging

That's because you're subscribing to the same symbol twice. The server sees that as the same subscription, so when you unsubscribe one they'll both unsubscribe. If you change the symbol on one of the two it'll work correctly.
