Add comprehensive tests for XML parser functionality

- Introduced benchmark tests for various XML parsing methods, including parsing from strings, bytes, and readers, to evaluate performance. - Added unit tests for the parser interface and validation mechanisms, ensuring robust error handling and validation logic. - Implemented tests for utility functions related to XML processing, enhancing overall test coverage and reliability. - Created a test suite for the TED domain, validating the structure and functionality of contract notices and related entities. - Developed a comprehensive test runner script to facilitate automated testing, coverage analysis, and performance benchmarking for the XML parser package.
