BirdNET debug (#370)

* feat: add debug flag for BirdNET processing

- Introduced a new debug mode option in BirdNETConfig to enable detailed logging during analysis.
- Set default value for debug mode to false in the configuration settings.

* feat: add BirdNET debug logging for result analysis

- Updated the debug logging mechanism in the BirdNET processing function to print all results when debug mode is enabled.
