Data Annotation Result

Since the annotation results are stored at the granularity of data, the data annotation result format needs to support both internal storage and import/export scenarios.A data may be labeled by multiple sources, and the labeling results need to be distinguished by source.
1.Object means Cuboid, and each Cuboid belongs to a certain Tracking Object. Note that a Tracking Object in a single frame may also contain multiple Cuboids (such as LiDAR-camera fusion dataset). The Object ID is UUID;
2.The import/export is based on the internal storage format, but the information used only internally, such as meta info, is removed;
3.Some information is not used when importing, but is needed for internal storage, it will be automatically added when importing, such as Object id, version, createdBy, createdAt, etc. Conversely, some redundant information is not stored in the internal storage, but needs to be added when exporting; 
4.Point cloud segmentation needs to store the point information in a separate file, and record the file URL in JSON to avoid JSON being too large. When importing/exporting, if the file is divided by Data, the point information can be directly placed in the file.
