Refactor parse_logger to handle structured logger records with error …

[zangjiucheng]

This pull request includes a significant rewrite of the parse_logger function in parsley/parsley.py to improve its robustness, readability, and adherence to the expected logger record format. The new implementation introduces structured parsing with validation and error handling.

Changes to parse_logger function:

• Improved Input Handling:

  • Changed the input type from str to bytes to align with the binary format of logger records.

• Logger Record Parsing:

  • Added a detailed docstring explaining the binary layout of the logger record, including the structure of the header and payload.
  • Introduced the use of the struct module for parsing the header (SID, timestamp, and DLC) in a structured and endian-aware manner.

• Validation and Error Handling:

  • Implemented validations for logger record structure, including checks for the "LOG" signature, header completeness, SID constraints, DLC range, and payload length. Raises ValueError for any structural issues.

• Logging for Debugging:

  • Added a print statement to log parsed values (page_number, SID, timestamp, DLC, and data) for debugging purposes.…handling
