Rust_isolate header

[DeviPriya-Kolla]

Description:
This issue involves developing functionality to extract and isolate the header metadata section of a TBE file, converting it into a Rust-native data structure.

Developer Notes:

• Create a dedicated Rust struct (e.g., TBEHeader) to represent the metadata fields extracted from the TBE header, including any hierarchical relationships between sections such as TBL sections and ATT attributes.
• Utilize Rust's log crate or standard output to provide logging capabilities for detected anomalies and processing steps during header extraction.

Acceptance Criteria:

• Store Metadata in a Rust Data Structure
• TBL sections and ATT attributes should be nested within the Rust structure to reflect the hierarchical organization of the original TBE header
• Mirrored TBE Header Structure
• Separate Attributes within Each TBL Section
• Error and Warning Handling for Missing or Unexpected Fields
• Ensure the function adheres to Rust programming standards and practices, allowing for seamless integration with other Rust codebases
