0.2.0-alpha23

Available on NuGet.

Changes:

• BREAKING: Change StreamAsync methods to SubscribeAndStream for all WebSocketClients and Caches.
  • Create new StreamAsync extension methods for all WebSocketClients and Caches that only streams.
  • BREAKING: SymbolStatisticsWebSocketClient and SymbolStatisticsCache StreamAsync() behavior changed (no longer automatically subscribes to all symbols).
• Add Open and Close event to IBinanceWebSocketClient and IBinanceWebSocketStream (#38).
• Add exception to enforce non-reentrancy of IWebSocketClient.StreamAsync if called from Close event (#41).
  • Change IsStreaming behavior (flag now set before connecting and cleared after Close event raised).
• Allow BinanceWebSocketStream.Subscribe while streaming with a log warning if stream is new (requires restart to take effect, but if only adding a callback restart is not required).
• Update WebSocketSharp and WebSocket4Net implementations.
• Update sample applications.
