Looks good, but two things:

1. While David works on Add centroid finder block #7, do you mind merging it into this branch or just copying the new structure for LabelsReader from here? It works at the frame-level now instead of instance-level.
2. Do you have pydocstyle in vscode? It looks like some of your docstrings are going over 88 characters per line. Ignore if I'm just eyeballing that wrong.

Sure, I'll merge my code with #7. I dont think I have pydocstyle, I'll check and add it now
