庆军之FastTunnel中转服务端加载证书

问题，仅在中转服务端加载证书，客户端不需要使用证书，方便证书过期了，仅在服务端加载即可。

解决方案：

ForwardDispatcher.cs

DispatchAsync中处理

using (var stream1 = await tcs.Task.WaitAsync(TimeSpan.FromSeconds(10)))
using (var stream2 = new NetworkStream(_socket, true) { ReadTimeout = 1000 * 60 * 10 })
using (SslStream stream = new SslStream(stream2))
{
stream.AuthenticateAsServer(Get(),false,false);//证书的处理

await Task.WhenAny(stream1.CopyToAsync(stream), stream.CopyToAsync(stream1));
}
