Review comment:
I recall a refactor concerning taking addresses of non-lvalues, due to
this we have some (not horribly many) instances of creating local callbacks for
the sole purpose of taking their addresses, creating a `ProcessSession(const
shrd_ptr<FF>&, OutputStreamCallback&&)` would handle these "forwarding"
use-cases (where the temporary callbacks only forward the stream data in some
implementation dependent manner),
I just would like to avoid the proliferation of "input/output-dependent"
methods on `ProcessSession` (like `writeFile`, `writeRawBuffer`, `writeString`,
etc.)
