Pull request overview
This PR enhances the parser generator to properly differentiate between YOLO model subtypes and leverage native DepthAI detection parsers where supported, instead of defaulting to YoloExtendedParser for all YOLO models. The implementation adds special handling for YOLO segmentation models on RVC2 devices, which must run parser logic on the host.
Changes:
- Added logic to check YOLO subtypes against a list of models supported by
dai.DetectionParser - Implemented RVC2-specific handling for segmentation models to force host-side parsing
- Added logging to inform users when segmentation mask processing occurs on the host

Purpose
Current implementation of parser generator preffers YoloExtendedParser for all YOLO models even though most models are now directly supported in
dai.DetectionParser. One caveat is in the case of YOLO segmentation on RVC2 where dai only supports running the parser on the host side.Specification

Testing & Validation
Tested on oak-examples generic example with the following models (both on RVC2 and RVC4):
Other models (yolo-p, yolo-world, yolo-e) crash their respective examples as oak-examples need to be updated to accmodate the change in segmentation mask.
