Added converter from poses dataset to bounding boxes dataset.

Feature: Pose → Bounding Box Converter

Hi maintainers;

This PR implements a utility to convert pose (keypoint) datasets into bounding box datasets, as discussed in Issue #17.

Summary

• Computes per-frame, per-individual bounding boxes from pose keypoints
• Handles missing/NaN keypoints
• Supports optional padding
• Returns an xarray-compatible bounding box dataset
• Includes a basic unit test

This functionality enables interoperability between pose-based tracking data and bounding box workflows (e.g., visualization, detection, segmentation pipelines).

I’d be very happy to refine the implementation further based on your feedback(as this is my first contribution to the movement repo) --especially regarding dataset schema alignment or integration preferences.

Thank you
