Depth Data Saving Integration

• Integrated --save-depth flag into calibrate_extrinsics.py.
• Uses aruco.depth_save.save_depth_data to persist HDF5 files.
• Captures:
  • Intrinsics and resolution.
  • Pooled depth and confidence maps.
  • Pool metadata (RMSE comparison, fallback reasons).
  • Raw candidate frames (depth, confidence, score, frame index).
• Logic is guarded: only runs if verify_depth or refine_depth is enabled.
• Added integration test tests/test_depth_save_integration.py using mocks to verify data flow without writing actual HDF5 files during testing.
