Enhance Filtering of Annotations by Model and Class in BaseFormat

[shamspias]

Summary:

This merge request introduces enhancements to the BaseFormat class, adding the capability to filter annotations based on model type (RTDETR, NAS, YOLO) and ensure that only classes specified in the project's YAML configurations are annotated. This change ensures annotations are not only accurate but also relevant to the specific models and use cases.

Changes:

• Model-Specific Annotation Processing: Updated the process_results method to incorporate checks that validate the model type before processing annotations. This ensures that annotations are generated appropriately according to the model type used (RTDETR, NAS, YOLO).
• Conditional Class Inclusion: Annotations for each class are now included only if the class identifier exists within the supported_classes list derived from YAML configuration files. This prevents irrelevant class annotations from being processed.

Benefits:

• Enhanced Accuracy and Relevance: By ensuring annotations are only created for supported classes and specific model types, the quality and applicability of training data are significantly improved.
• Increased Flexibility and Configurability: Facilitates easy adaptation to different models and class sets by adjusting YAML configurations, enhancing the system's usability across various datasets and requirements.
• Streamlined Annotation Process: Reduces computational overhead and potential errors by filtering out irrelevant classes early in the annotation process.
