Implementation of Panoptic Quality metric

[csudre]

Is your feature request related to a problem? Please describe. The panoptic quality allows to account simultaneously in instance segmentation issues for detection and segmentation quality. It requires however to be able to find true positive elements

Describe the solution you'd like Add the panoptic quality as possible metric to be used in instance segmentation problems The PQ is defined as \dfrac{\sum_{p,g}IoU(p,g)}{|TP|} x \dfrac{|TP|}{|TP|+1/2|FP|+1/2|FN|} i.e the average of the IoU over the true positive elements multiplied by the detection F1 score.

hi @csudre!

I would like to help implement the metric. Do you think you help me get started, like under which I module I should start implementing the metric.
