iana-time-zone 0.1.65, patched for Oxygen

The crate as published on crates.io (MIT OR Apache-2.0, see LICENSE-*), with one change: on Apple targets the time zone is read from /etc/localtime, as on Linux, instead of through CoreFoundation, so the crate needs no Apple framework and the macOS cross build links. It is pulled in by chrono's clock feature through object_store, which only ever uses UTC. Used through [patch.crates-io] in the workspace Cargo.toml.
