docs: Reads one item from the Ringbuffer. If the sequence is one beyond the current tail, this call blocks until an
          item is added. Currently it isn't possible to control how long this call is going to block.
  
          :param sequence: (long), the sequence of the item to read.
          :return: (object), the read item.
