feat(layoutreader): support local model directory and improve model loading

Added a link to the layoutreader repository in the Related Projects sections of both the README.md and README_zh-CN.md files. This addition helps to provide users with more resources and tools related to document layout analysis and processing.

docs: update model download instructions for version 0.9.x and later- Add note about separate download for layoutreader model in version 0.9.x and later
- Include example code for downloading layoutreader model using ModelScope
- Clarify that previous download methods do not support updating to version 0.9.x and later

- Add function to get local LayoutReader model directory- Check and use local model directory if available
- Fall back to online model if local directory not found
- Update model initialization to support local path
- Refactor model loading in singleton class

fix: caption|footnote match algorithm

fix: caption or footnote match algorithm

perf(pdf_extract_kit): conditional memory cleanup based on GPU capacity

- Introduce a conditional memory cleanup step in the PDF extraction process
- Assess available GPU memory before deciding to perform memory cleanup- Log the time taken for garbage collection when it occurs
- This optimization helps to balance performance and resource utilization

feat: add arXiv paper link to header and adjust PDF parsing logic

feat: add arXiv paper link to header and adjust PDF parsing logic- Add arXiv paper link to the header template for easy access to the latest research paper.
- Modify the PDF parsing logic to handle edge cases more accurately, particularly in determining the number of lines in a block based on its height.

refactor(model): improve timing information and performance

- Enhance timing output precision to two decimal places for better readability- Calculate and log document analysis speed in pages per second
- Optimize logging for YOLO and table recognition processes
- Remove unnecessary comments and improve code efficiency

add arxiv url

add arxiv url

feat：add layoutreader to sort blocks

- Insert lines into blocks based on median line height- Calculate block index using line indices median
- Remove virtual line information for table and image blocks
- Enhance line sorting algorithm for different block types
- Add line height calculation function

The clean_memory function has been removed from pdf_parse_union_core_v2.py due to it not being used.
This change streamlines the code and prevents potential confusion regarding its purpose.

Update import statements in `pdf_parse_union_core_v2.py` to directly import
`prepare_inputs`, `boxes2inputs`, and `parse_logits` from `magic_pdf.model.v3.helpers`
instead of from `magic_pdf.model.v3`. This change streamlines the imports, making the
code more readable and maintaining a cleaner approach to modular design.
