Exclude folders from `--unreferenced=reject` checks

In the crates.io codebase we have a mix of Rust and JS code. We use `insta` for a lot of the Rust code, and increasingly `vitest` for the JS code. We use `cargo insta test --require-full-match --unreferenced=reject` to run the Rust test suite on CI. This worked fine until we tried to use the snapshot feature of `vitest`, which unfortunately also creates `.snap` files. These files now get picked up by `cargo-insta` and reported as unreferenced insta snapshots. Is there some way to influence what paths are relevant to the "unreferenced snapshots" detection? What I've seen so far are options for gitignored and hidden files, but those unfortunately won't solve our issue. If there is no such option yet, would there be interest in supporting such a use case? I'm happy to do the implementation work, but we should probably first talk about how this should look like to the enduser :)
