streaming export

[Eldies]

Motivation and context

When we export a dataset, all annotations are kept in RAM. It may be a problem if they are large.
Enabling streaming export for task or job data, for yolo formats

depends on cvat-ai/datumaro#81, cvat-ai/datumaro#90, cvat-ai/datumaro#94

How has this been tested?

I've noticed export performance degradation in streaming mode for COCO formats, about 2-3x in my cases. As I understand it, the problem is in coco/exporter.py:142, where the regular json library is used instead of the optimized orjson. I suppose orjson isn't compatible directly with json stream used in the implementation now, but I could find that there is other relevant functionality in orjson - https://github.com/ijl/orjson?tab=readme-ov-file#fragment. Please check this issue.
