docs: Finish a previous asynchronous RPC.
  
          This method should be called by a peripheral tile that previously
          had an RPC called on it and chose to response asynchronously by
          raising ``AsynchronousRPCResponse`` in the RPC handler itself.
  
          The response passed to this function will be returned to the caller
          as if the RPC had returned it immediately.
  
          This method must only ever be called from a coroutine inside the
          emulation loop that is handling background work on behalf of a tile.
  
          Args:
              address (int): The tile address the RPC was called on.
              rpc_id (int): The ID of the RPC that was called.
              *response: The response that should be returned to the caller.
  
                  This can either be a single bytes or bytearray object or a
                  str object containing the format code followed by the required
                  number of python objects that will then be packed using
                  pack_rpc_payload(format, args).
  
                  If you pass no additional response arguments then an
                  empty response will be given.
