Add Head Orientation Node for ComfyUI to custom node list (#1030)

This pull request adds the Head Orientation Node for ComfyUI to the custom node list. 

Key features of the Head Orientation Node:
- Analyzes and sorts images based on facial orientation using MediaPipe
- Detects facial landmarks and calculates head pose (pitch, yaw, roll)
- Supports batch processing of multiple images
- Enhances AI image processing workflows with intelligent image sorting

Technical details:
- Implemented in Python using MediaPipe, OpenCV, and NumPy
- Compatible with existing ComfyUI infrastructure
- Thoroughly tested for accuracy and performance

This node fills a gap in the current ComfyUI ecosystem by providing advanced facial analysis capabilities, which can be particularly useful for tasks like:
- Automated portrait retouching
- Dataset preparation for facial recognition models
- Creating consistent facial animations

The code follows best practices for Python development and adheres to the Apache 2.0 license, ensuring compatibility with ComfyUI and its extensions.

I've thoroughly tested this node and believe it will be a valuable addition to the ComfyUI toolkit. I'm open to any feedback or suggestions for improvement.

Thank you for considering this contribution to the ComfyUI-Manager repository.
