Refactor package structure for logger to include versioning.

Moved all logger-related classes to the `nl.astraeus.logger.v1` package to introduce versioning and improve maintainability. Updated logic in `StringArrayRing` to filter out blank lines during data retrieval. This change establishes a foundation for future updates without breaking compatibility.
