DynamicBuffer_v1: Remove characters from the input sequence. DynamicBuffer_v2: Consume the specified number of bytes from the beginning of the underlying memory.
void consume( std::size_t n);
          DynamicBuffer_v1: Removes n characters from the beginning of the
          input sequence.
        
          If n is greater than the
          size of the input sequence, the entire input sequence is consumed and no
          error is issued.
        
          DynamicBuffer_v2: Erases n bytes from the beginning of the vector.
          If n is greater than the
          current size of the vector, the vector is emptied.
