Thanks, I know this, but this is not a known format that can be easily
parsed like a plain CSV file. At least the way the SITI filter is
used, regular users just want simple output in a file that they can
directly load into Excel, Python, whatever. (Just like for VMAF.)

I understand why you wouldn't want each filter to have its own IO
functionality, but in terms of usability, only having the metadata
option would be extremely bad.

(Perhaps the real solution would be to have the metadata filter
generate different kinds of known output formats.)
