ffcine-ingest 0.4.0

//! Card offload and the clip catalog, with no GPU or libav dependency so it runs on the Mac in
//! the van: [`ingest()`] copies camera cards with BLAKE3 verification, a manifest and an
//! optional backup; [`clock`] applies per-camera clock/zone fixes and flags disagreeing clocks;
//! [`catalog`] indexes clips with format and picture profile (`docs/ingest.md`).
