- Update OCR utils to handle different box formats and improve angle calculation
- Modify PDF extraction kit to support OCR option and optimize processing flow
- Enhance PPOCR model to sort and filter detection boxes, improving text splitting accuracy

- Improve logic to skip dropped spans in overlap detection
- Enhance efficiency by avoiding unnecessary comparisons

- fix the bug where hyphens in the middle of a line are being discarded

- Add threshold parameter to merge_spans_to_line function
- Make threshold configurable for y-axis overlap check
- Improve flexibility and accuracy of line merging algorithm

- Check if language string is empty and set it to None
- This prevents potential errors when an empty language string is passed

- Introduce a variable threshold for right margin based on block width
- Use 0.26 * block_weight for wider blocks (block_weight_radio >= 0.5)
- Use 0.36 * block_weight for narrower blocks- This change aims to improve paragraph splitting accuracy for different block widths

- Add albumentations package with version <=1.4.20 for old_linux
- This version is compatible with Linux systems from 2019 and earlier
- Version 1.4.21 and above introduced simsimd which is not supported on older Linux systems

- Add page size information to blocks
- Calculate block width ratio relative to page width
- Adjust threshold for determining right side indentation
- Implement additional checks for merging blocks across pages
- Improve logic for identifying list structures

feat(ocr): improve handling of angled text boxes

- Add calculate_is_angle function to detect angled text boxes
- Update update_det_boxes and merge_det_boxes functions to handle angled text boxes
- Modify angle detection logic in various parts of the code

refactor(tests): extract common test utilities into test_commons.py

test(unitest): Restore unit test cases

update ci

docs: update feature description for table conversion

- Changed the description for table conversion feature in both English and Chinese README files
- Specified that tables are automatically converted to HTML format instead of LaTeX or HTML

docs: improve GPU support list formatting in README_zh-CN.md

- Adjust spacing and line breaks in the GPU support list for better readability

docs(README): update GPU hardware recommendations and table recognition options

- Simplify GPU recommendations to 8GB or more, removing separate minimum and recommended configurations
- Update list of supported GPUs for8GB and above
- Update table recognition options in config settings

docs(README): update project references and translations

docs：update docs for 0.9.3

refactor(model): rename and restructure model modules

- Rename ppTableModel to TableMasterPaddleModel in test_tablemaster.py

fix(parse_pipeline): Resolve post-processing exceptions caused by partial PDFs due to file corruption or non-standard format by forcing a re-print.
