Add Transmission Control Protocol file handling and update PCL serialization

- Introduced FileRead and Record classes for handling file reading in the Transmission Control Protocol.
- Enhanced Description, Detail, and other related classes with JSON serialization attributes for improved data handling.
- Implemented methods for reading and processing files, including network stream management.
- Updated unit tests to cover new functionality and ensure robust testing.
- Added new PDSF file handling classes and integrated them into the project structure.
- Refactored existing code to utilize source generation for JSON serialization, improving performance and maintainability.
