refactor(sterni/mblog): move REDIRECT-STREAM into mime4cl r/6154
Eventually, we'll want to replace dump-stream-binary with something more efficient—given that we have flexi-streams we can use something that only does matching element types no problem. REDIRECT-STREAM is much more efficient thanks to using an internal buffer. streams.lisp gets a new section at the beginning for grouping utilities that don't have any real (internal) dependencies.
