Refactor: BinaryImporter optimization + javadoc

[capdevon]

This PR improves the BinaryImporter class by modernizing its code and enhancing maintainability:

• Updates copyright years.
• Replaces wildcard imports with explicit imports.
• Adds comprehensive Javadoc comments to public methods for better documentation and usability.
• Refactors resource management by using try-with-resources for streams to prevent resource leaks.
• Improves logging, especially for debug statistics.
• Changes some method visibilities and names for better encapsulation and clarity.
• Performs minor formatting and cleanup for code consistency.

These changes make the codebase easier to understand, safer, and more maintainable, while preserving existing functionality.

Does this Javadoc provide any non obvious information?

An empty default constructor clearly just creates a new instance. However, Javadoc for every constructor is a standard and necessary practice for the Java API. It ensures generated documentation is complete and maintains consistency throughout the project's style. Even if the content seems minimal, its presence is expected.

Raising questions on these well-established conventions slows down the review without adding significant value, and it takes away valuable time that could be dedicated to more complex and relevant code issues.
