Support rotated bounding boxes in automatic annotation

We are using CVAT's automatic annotation tool Nuclio

We wrote a custom YoloV5 detector with our own model

YoloV5 supports rotated rectangle detection in the following format [x, y, w, h, theta] where theta is the rotation angle

CVAT automatic annotation also supports attributes returned from Nuclio functions, as seen in this issue 5306

After inspecting the source code, rotation is considered as attributes by CVAT too but adding this to the response payload did not help 'attributes': {'name': 'rotation', 'input_type': 'number', 'value': angle} where angle is a number, returned by the YoloV5 detector

Directly returning 'points': [x, y, w, h, theta] yields the error "Got 2.5 points"

Current Behaviour

Rotation returned from Lambda function is not used by CVAT

Possible Solution

Allow CVAT to also accept a rotation parameter from the Lambda function and make use of it in the handler, adding rotation in the attributes field of an annotation
