Add robust logging support to the Filter class

[Thavarshan]

Overview

This Pull Request introduces a logging mechanism into the Filter class, enhancing debugging and operational monitoring capabilities. This feature allows developers to enable or disable logging at runtime, providing valuable insights into the filter application process, which is critical for both development and production environments.

Details

The modifications include:

• Integration of the Psr\Log\LoggerInterface to support flexible logging strategies.
• Methods to enable and disable logging, which helps control logging behavior dynamically.
• Conditional logging throughout the filter processing methods to record key actions and decisions, enhancing traceability and troubleshooting.
• Unit tests to ensure the logging functionality works as expected under various conditions.

Implications

With the introduction of logging:

• Developers can now track the filter application process more transparently.
• It becomes easier to diagnose issues and understand the behavior of the Filter class in complex scenarios.
• The feature is optional and can be turned on or off, ensuring that performance is not impacted when logging is not required.
