Construct an address from raw bytes.
address_v4( const bytes_type & bytes);
            Initialises the address_v4
            object such that to_bytes() == bytes.
          
                  Thrown if any element in bytes
                  is not in the range 0 - 0xFF.
                  Note that no range checking is required for platforms where std::numeric_limits<unsigned char>::max() is 0xFF.
