WebsocketDisconnected and WebsocketReconnected are non-generic AsyncEventHandlers

[Nixill]

In both version 0.5.0 (highest version number) and 0.5.0-preview-abba5e7 (actually most recent), the EventSubWebsocketClient handlers WebsocketDisconnected and WebsocketReconnected are non-generic and require a handler with a second parameter of type EventArgs rather than a specific event type. In the case of Disconnected, the type WebsocketDisconnectedArgs exists; this is not true of the Reconnected event.
