control.protocol.unescape_output(source: &[u8]) -> Vec<u8>
```

Undo the escaping tmux applies to `%output`.

tmux writes a byte below `0x20` as `\ooo` and a backslash as `\\`, and
leaves everything else alone -- so a pane emitting Latin-1 or binary
produces a line that is not UTF-8. Anything else after a backslash is not
an escape tmux produces, so it is kept as written rather than guessed at.
