        Description copied from interface: RequestHandler
        Handles the received Radius packet and constructs a response. Filters/Deduplicators can also implement this and wrap around underlying handlers.
        Specified by:
        handlePacket in interface RequestHandler<T extends RadiusPacket,SecretProvider>
        Parameters:
        channel - socket which received packet
        request - the packet
        remoteAddress - remote address the packet was sent by
        secretProvider - shared secret associated with remoteAddress
        Returns:
        null if packet is considered duplicate, otherwise delegates to underlying handler.
