- Updated type hints across multiple files to replace `Optional[X]` with `X | None` for better readability and consistency.
- Added `from __future__ import annotations` to files to enable postponed evaluation of type annotations.
- Adjusted function signatures and variable types in various modules including `polygon_zone.py`, `smoother.py`, `transformers.py`, `vlm.py`, and others.
- Ensured compatibility with Python 3.10+ type hinting features.

Refactored import paths for test utility methods across multiple test files to align with a recent package restructure. Enriched 'read_txt_file' functionality in 'file.py' allowing to optionally skip empty lines, enhancing flexibility for various use-cases. Added tests for the new 'read_txt_file' behavior in a new 'test_file.py'. Renamed 'utils.py' in test package to 'test_utils.py' for better differentiation from the util package in the source code.
