[Feature Request] Add CLI option to check specific files

I'd like to run this as a pre-commit hook and only check staged files so I can
1) Make sure no regressions are checked in
2) Check that new files aren't checked in with the ignore comment.

I think I could achieve 1) myself by creating a temporary tsconfig.json file with the staged files listed as `files` and feed that to the CLI, but it would be much better if the command could directly handle a list of files.

Is that technically possible?

For 2), I would also appreciate exposing a new cli command which takes a list of files and throws an error if any of them are ignored
