You can test this by (say) adding `foobar = 42` to Clippy's root `clippy.toml` file, and running `cargo run --bin cargo-clippy`.

Note that, to get the terminal width, this PR adds `termize` as a dependency to `cargo-clippy`. However, `termize` is also [how `rustc_errors` gets the terminal width](481db40311/compiler/rustc_errors/src/emitter.rs (L1607)). So, hopefully, this is not a dealbreaker.
