Receiving heartbeat logs internal error message.

[daerhiel]

Describe the bug When subscribing to Bittrex Heartbeats the error is logged internally every time the message is received from server.

To Reproduce Subscribe to the heartbeat with the following call:

        var client = serviceProvider.GetRequiredService<IBittrexSocketClient>();
        _heartbeat = await client.SpotStreams.SubscribeToHeartbeatAsync(OnHeartbeat).ToException(Descriptor);

Expected behavior I guess there's a problem with deserializing the timestamp from heartbeat message.

Debug logging

Hi, this was an issue when using the HeartBeat subscription in combination with other subscriptions. It has been fixed in the latest version
