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

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.

Adapt import statements in `pdf_parse_union_core_v2.py` to reflect the updated packagestructure, changing from the `magic_pdf.v3.helpers` module to the `magic_pdf.model.v3`
module. This ensures compatibility with the revised directory layout.

Blocks without lines are now correctly indexed even when they contain textual content rendered
as images. The sorting logic has been updated to accommodate this scenario. Additionally, the
LayoutLMv3 model initialization has been enhanced to utilize bfloat16 precision on devices that
support it, offering potential performance benefits on supported hardware.

Removed redundant sorting of lines by model and optimized calculation of block
indexes by using a single pass through the sorted lines. This change simplifies the
code and potentially improves performance by reducing the number of sortingoperations and unnecessary iterations over blocks without lines.
