Summary

Fixes #20

The problem required exporting from CVAT with images in Datumaro format, so users had problems with the format.

  • Fix broken type inference for DatasetItem.media_as()
  • Remove duplicated 'media' field in the datumaro format export
  • Add PointCloud to the datumaro import namespace
  • Add tests for the issue and datumaro dataset examples
  • Fixed comparison for PointCloud objects

Depends on cvat-ai/datumaro#34

This PR improves quality of life when using Datumaro format.

- Added support for direct .json uploading of annotations, similarly to
the COCO and CVAT formats
- Added image metadata when exporting in the Datumaro format without
images
- For related images in 3d tasks, datumaro export without images will
include only the basenames (before: absolute server paths were exported)
- <s>Refactored `conv_mask_to_poly` uses to avoid code and logic
duplication</s> (will be in another PR)
