Add `episodes_per_video_file` to `episodes_factory`: episode `i` goes to
`file_index = i // episodes_per_video_file` and `from_timestamp` restarts at 0 on
each rollover. `create_videos` encodes one .mp4 per file, and
`mock_snapshot_download` lists and creates every video file rather than only
file-000. Without the option the fixtures emit the same single-file layout as
before.
Add streaming tests over that layout, on the plain and the delta path.
* refactor(datasets): replace untyped dict with typed DatasetInfo dataclass
Introduce typed DatasetInfo dataclass to replace untyped dict representation of info.json.
Changes:
- Add DatasetInfo dataclass with explicit fields and validation
- Implement __post_init__ for shape conversion (list ↔ tuple)
- Add dict-style compatibility layer (__getitem__, __setitem__, .get())
- Add from_dict() and to_dict() for JSON serialization
- Update io_utils to use load_info/write_info with DatasetInfo
- Update dataset utilities and metadata to use attribute access
- Remove aggregate.py dict-style field access
- Add tests fixture support for DatasetInfo
Benefits:
- Type safety with IDE auto-completion
- Validation at construction time
- Explicit schema documentation
* fix pre-commit
* update docstring inside DatasetInfo.from_dict()
* sorts the unknown to have deterministic output

* refactoring the last few old fieds
* fix crop dataset roi type mismatch
* use consistantly int for data and video_files_size_in_mb
