About visualizing the detections

[tianyxOoO]

Hello!
Thanks for your detailed introduction!
When I was trying the "run example" part, I successfully ran the "python scripts/run_test_interframe.py". Then I tried to visualize the detections with "python scripts/visualize_detections.py", but I found no "extract_image_by_index" and "load_start_and_end_time" functions in the "dsec-det/src/dsec_det/io.py".
Could you please upload the missing part of the code?
Thank you very much!

Best wishes!
