Multiplexer module for ISO communication

This module starts and SDP server and waits for incoming V2G connections (TCP, and optionally TLS). Upon connection, it reads the SupportedAppProtocol.req message to determine if the EV supports ISO-20 or not. If ISO-20 is supported, it transparently bridges the connection to the ISO-20 module (using TLS->TCP). If the EV does not support ISO-20, it bridges to the ISO-2 module instead. Both the required iso-2 and iso-20 modules only need TCP enabled, but they require to accept e.g. PnC on TCP sessions (as the actual communication to the EV may be TLS). Also the need to listen on localhost (::1) instead of the actual PLC device. Signed-off-by: Cornelius Claussen <[email protected]>
