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
