Multi connection

In lightyear, the server can handle multiple connection protocol as the same time. This means that the server could:

• open a port to establish steam socket connections
• open another port for UDP connections
• open another port for WebTransport connections
• etc.

and have all these connections running at the same time.

You can therefore have cross-play between different platforms.

Another potential usage is to have a "ListenServer" setup where a client acts as the "host":

• the Client and the Server run in the same process
• the Server has multiple connection protocols:
  • one is based on local channels to talk to the Client that is running in the same process
  • the other could be for example a UDP connection to allow other clients to connect to the server

To achieve this, you can just provide multiple NetConfig when creating the ServerConfig that will be used to create the server.
