Boost.Iostreams is a library dedicated to making creation of new stream
types easier.

Having said that, it's still rooted in the C++03 world, so it might be
missing some potential optimisations from modern C++. Mind you, so are

Surprisingly, it doesn't look like Iostreams already has a concatenating
Source, which seems like it might have been a good fit for your use case
and the library itself. Perhaps you could contribute one?
