Add detectron2

Want to do hand/body tracking with detectron2

[mjsobrep]

We would want to use R101-FPN from https://github.com/facebookresearch/detectron2/blob/main/MODEL_ZOO.md#coco-person-keypoint-detection-baselines-with-keypoint-r-cnn Could also try the X101 model, but its performance is not much better for the large jump in compute cost.

A nice example of how to get detectron running is here: https://colab.research.google.com/drive/16jcaJoc6bCFAQ96jDe2HwtXj7BMD_-m5#scrollTo=GYJrlXZC5M-J&line=3&uniqifier=1

Things that may need to be added:

• new docker file: https://github.com/Rehab-Robotics-Lab/FloAssessmentPipeline/tree/master/dockerfiles
• build and run commands in bash wrapper: https://github.com/Rehab-Robotics-Lab/FloAssessmentPipeline/blob/master/pose/src/run_local.sh
• A new wrapper file, similar to: https://github.com/Rehab-Robotics-Lab/FloAssessmentPipeline/blob/master/pose/src/openpose_wrapper.pyv
• Add to the hdf5 processing script: https://github.com/Rehab-Robotics-Lab/FloAssessmentPipeline/blob/master/pose/src/process_hdf5.py
• Implement in wrist overlay: https://github.com/Rehab-Robotics-Lab/FloAssessmentPipeline/blob/master/visualize/video_overlay/overlay_wrists.py
• Implement in skeleton overlay: https://github.com/Rehab-Robotics-Lab/FloAssessmentPipeline/blob/master/visualize/video_overlay/skeleton_overlay2d.py
