Bug: Target["area"] incorrect when using selective_search (and possibly others)

[AZaitzeff]

The selective_search function changes the boxes to xyxy coordinates. boxes[..., 2] = boxes[..., 0] + boxes[..., 2] boxes[..., 3] = boxes[..., 1] + boxes[..., 3]

In [__get_item__] (https://github.com/amirbar/DETReg/blob/36ae5844183499f6bc1a6d8922427b0f473e06d9/datasets/selfdet.py#L67)
we have boxes = selective_search(img, h, w, res_size=128) ... target['boxes'] = torch.tensor(boxes) ... target['area'] = target['boxes'][..., 2] * target['boxes'][..., 3]

But boxes at this point on in xyxy not cxcywh, So the "area" is incorrect. I do not know if this effects anything down the line, it may not.

After looking through the code I am pretty sure that "area" never gets used
