SPAD Video Support

Main Changes

1. New function: create_video_from_frames()

• Generates MP4 videos from generated SPAD frames (PNGs)
• Converts a sequence of numerically ordered images into a video
• Includes directory validation and error handling

2. New command-line arguments

-- save_spad_video / -sv: Flag to enable MP4 video generation from SPAD frames
-- spad_video_dir / -svd: Output directory for the MP4 video (default: output_dir)

3. Integration into main stream

• Upon completion of SPAD frame generation, if --save_spad_video is enabled, the video is automatically created
• The video is saved as spad_frames.mp4
• Includes exception handling to prevent failures if video generation is unsuccessful
