Access Non-Axis-Aligned Bounding Boxes

Hi all,

Based on my understanding, Textract provides an axis-aligned BoundingBox object and a Polygon object which is composed of more specific points (https://docs.aws.amazon.com/textract/latest/dg/text-location.html). It seems that Textractor only provides the BoundingBox object.

When documents contain significant skew or rotation, axis-aligned boxes will be much larger than non-axis-aligned boxes, and they won't neatly match up with the actual position of the text.

I've attached an example input document, an output text layer using Textractor results, and an output text layer from a different OCR inference that provided non-axis-aligned bounding boxes to hopefully make this easy to visualize.

Is it possible to add the Polygon object in Textractor? It would be a big help!
