Importing dataset in cvat format loses angle

[dreambit]

When i export my dataset in cvat format and then import it - all bboxes are without angle(angle is reset to 0)

Might be related with #4745, but I am not sure.

Need to check if it is reproduced additionally.

Looks like here we need fix on datumaro side. I expect attributes field to contain rotation as it implemented for occluded after this line Dataset.import_from(tmp_dir, 'cvat', env=dm_env).

The bug happens when we export/import a project.
