Update main.py

[ajay-khichi]

Exception Handling:
Added try-except blocks for critical processes like model loading (both predictor and object detection models).
This ensures graceful error handling and informative error messages if a model fails to load.

Dynamic Threshold and Skip Frames:
Made THRESHOLD_SCORE and SKIP_FRAMES configurable for easier tuning during runtime.
These parameters can now be adjusted without modifying the core logic.

Output Management:
Ensured the output directory (output/) is created if it doesn’t exist.
Integrated a cv2.VideoWriter to save processed video frames, ensuring the results are available in video format.

Progress Feedback:
Included print statements to provide progress feedback, such as model loading status and video processing updates.
Helps users monitor the script's progress during execution.

Video Saving Fix:
Resolved issues with saving processed frames into the output video file by correctly initializing cv2.VideoWriter.
