ENH: Add object detection model family, models, and datasets

[NickleDave]

• Add prep step for object detection datasets
• Add objection detection model family
• Add Deepsqueak model
  • Add Faster-RCNN that uses object detection model family
  • Add whichever version of YOLO they are currently using that uses object detection model family
• Should we also adapt voxaboxen? IIUC they only predict start/stop time but they are using OD models (something I keep thinking about doing, just to prove a point 🤔 😈 )
• Add related datasets that I think actually have bbox annotations, e.g. MUPET, MouseTube
