cli: switch from atty crate to is-terminal

The `atty` crate seems unmaintained. There's
https://rustsec.org/advisories/RUSTSEC-2021-0145 filed against it,
which `cargo-deny` complains about. A fix for that has been open for
well over a year without being fixed
(softprops/atty#51). The `is-terminal` crate
is a fork of `atty` with that fixed, plus some other changes.
