feat: ✨ yolov8-obb support and OrientedBoxAnnotator added for obb

[onuralpszr]

Description

This pull request introduces two significant features:

YOLOv8 Oriented Bounding Box (OBB) Support: This feature extends the capabilities of the YOLOv8 model to detect objects in images and provide oriented bounding boxes as output. This is particularly useful in scenarios where the orientation of the object matters, such as detecting vehicles or buildings from aerial images. The support for OBB allows the model to provide more precise and detailed information about the detected objects.

OrientedBoxAnnotator: This new class provides functionality for annotating images with oriented bounding boxes. This can be used to visually verify the output of the YOLOv8 model with OBB support or to create new training data. The OrientedBoxAnnotator makes it easy to draw oriented bounding boxes on images, which can be a complex task due to the need to handle the orientation of the boxes.

These features enhance the capabilities of the library in handling object detection tasks where object orientation is important. They also provide users with easy-to-use tools for working with oriented bounding boxes, both in terms of model output and data annotation.

@onuralpszr I decided to drop visual examples from docs for now. I need to think about a good place to show it. And I really need to wrap this PR before release. ;) But we will definitely add it in upcomming days.
