Description
As you probably know, `zstd` is famous for its fast (and stable) parallel compression capability. It would be great if `iostream` would teach the skill.
I've got a WIP parallel implementation of the `io::multichar_output_filter` filter:
[boost-zstd.cc.txt](https://github.com/boostorg/iostreams/files/12472545/boost-zstd.cc.txt)

Research direction
Start by reviewing the attached boost-zstd.cc.txt implementation and the io::multichar_output_filter interface. Trace the existing zstd filter behavior and test coverage before assessing how parallel processing fits. Done means the zstd filter supports parallel processing while preserving existing behavior.
