Rust_output CSV

[DeviPriya-Kolla]

Description:
This issue involves implementing functionality to export TBL sections from a TBE file into CSV format within a Rust environment.

Developer Notes:

• Develop a function, export_tbl_to_csv, that reads TBL sections from TBE files and structures them into CSV-compatible formats. Use Rust libraries such as csv or serde_csv for efficient CSV handling.
• Design the function to fit seamlessly within Rust applications, supporting use cases in both command-line tools and web applications (e.g., Actix or Rocket) for exporting data in response to user requests.

Acceptance Criteria:

• Export TBL Sections to CSV Format
• Attribute Mapping for CSV Headers
• Handle Multiple TBL Sections
  • Each TBL section as a separate CSV file
  • All TBL sections in a single CSV file
• handle cases of empty or malformed TBL sections
  • empty TBL sections will appear in the CSV as rows with blank cells rather than being skipped
  • For malformed sections (e.g., missing ATT attributes), provide a clear error message and attempt to skip or correct where feasible.
• ensure exported CSV files are opened correctly in common spreadsheet applications
