* Add checked prediction methods - Add checked prediction methods to ZeroShotClassificationModel. These methods return Option and convert any underlying errors into None, to allow callers to implement appropriate error handling logic. * Update ZeroShot example to use checked method. * Add tests for ZeroShot checked methods * Change checked prediction methods to return Result * refactor: rename *_checked into try_* Rename *_checked methods into try_* methods. This is more idiomatic vis-a-vis the Rust standard library. * refactor: remove try_ prefix from predict methods * refactor: change return from Option to Result Change return type of ZeroShotClassificationModel.prepare_for_model from option into Result. This simplifies the code, and returns the error closer to its origin. This addresses comments from @guillaume-be. * refactor: address clippy lints in tests Co-authored-by: guillaume-be <guillaume.becquin@gmail.com>
