Deny clippy::unwrap_used

You must either use expect() with a proper message, or do something that
won't panic.

I saw some crates (for an unrelated project idea) advertise this in
their docs, and it made me think of that bug I found by fuzzing the YAML
chunker. The next level would be to remove expect() too and promise
never to panic, but I don't know if I want to go all the way there.
My expect() uses all seem pretty reasonable.
