feat: Common result dataclasses and refactoring several methods. (#50)
* chore: Rename scripts to tools folder and unify argument parser * refactor: Centralize dataclasses in types.py and add __call__ to all models - Move Face and result dataclasses to uniface/types.py - Add GazeResult, SpoofingResult, EmotionResult (frozen=True) - Add __call__ to BaseDetector, BaseRecognizer, BaseLandmarker - Add __repr__ to all dataclasses - Replace print() with Logger in onnx_utils.py - Update tools and docs to use new dataclass return types - Add test_types.py with comprehensive dataclass testschore: Rename files under tools folder and unitify argument parser for them
