The Ipv6HopByHopRepr was previously the same as an Ipv6ExtHeader. However, the RFC says that hop-by-hop options might change, which is not possible with the current implementation. I added a representatation for the Hop-by-Hop header, which has an heapless Vec of parsed options. This way, we can modify the options when needed. The function of the Ipv6ExtHeader struct is now purely for parsing the ext header type and the length. It also returns a pointer to the data it holds, which must be parsed by the correct extension header representations.
