dhnsw::detail::query_engine is incompatible with recent changes to cereal::YGMInputArchive

[bwpriest]

Saltatlas DHNSW executables can no longer compile due to the following error:

  603 |     cereal::YGMOutputArchive oarchive(to_return);  // Create an output archive
      |                              ^~~~~~~~

This appears to happen because saltatlas::dhnsw::detail::query_engine reasons about raw std::vector<std::byte> buffers. Meanwhile, it appears that a recent commit to ygm/v0.7-dev (520916642aab511ce7261801812f5f10b88f8ee6) updated YGM to internally use ygm::detail::byte_vector. This means that cereal::YGMOutputArchive can no longer accept a raw std::vector<std::byte> in its constructor.

I fiddled with a few simple fixes, but I think that either ygm::detail::byte_vector needs to have const iterator accessors and an interface for inserting new bytes, or there need to be major changes made to saltatlas::dhnsw::detail::query_engine.
