Advanced Face Tracking & Occlusion Handling

NEW FEATURES:
- Face tracking with Kalman filter for stabilization
- Occlusion detection and handling (hands/objects)
- Advanced face mask creation with landmarks
- Stabilized face swapping (reduced jitter)
- Smart blending for occluded areas

 OCCLUSION IMPROVEMENTS:
- Detects when hands/objects cover the face
- Maintains face swap on face area only
- Skin detection for hand recognition
- Edge detection for object boundaries
- Smooth transitions during occlusion

 STABILIZATION FEATURES:
- Position smoothing with configurable parameters
- Landmark stabilization for consistent tracking
- Face template matching for verification
- Confidence-based tracking decisions
- Automatic tracking reset capabilities

 NEW FILES:
- modules/face_tracker.py - Advanced face tracking system
- test_improvements.py - Demo script for new features

 ENHANCED FILES:
- modules/processors/frame/face_swapper.py - Occlusion-aware swapping
- modules/live_face_swapper.py - Integrated tracking system

 USAGE:
- Run 'python test_improvements.py' to test new features
- Face swapping now handles hand gestures and objects
- Significantly reduced jittery movement
- Better quality with stable tracking
