sniff: separate mime type detection into its own command `sniff-type`

[jqnatividad]

In anticipation of refactoring the new sniff (#2247).

Replace the file-format crate with the file-type crate - https://github.com/theseus-rs/file-type?tab=readme-ov-file. It has broader file type coverage and better detection of spatial files.

Also consider using the https://github.com/google/magika crate by Google - AI-powered file content type detection.
