Own mAP implementation

[Borda]

[0.6.1] - 2021-12-06

Changed

• Migrate MAP metrics from pycocotools to PyTorch (Torch-based mAP #632)
• Use torch.topk instead of torch.argsort in retrieval precision for speedup ([precision.py] Wall-clock time speedup by performing top-k slicing at first and replacing argsort with topk #627)

Fixed

• Fix empty predictions in MAP metric (MAP metric - fix empty predictions #594, Map second fix empty preds #610, Fix MAP metric for empty cases #624)
• Fix edge case of AUROC with average=weighted on GPU (Fix weighted AUROC on gpu #606)
• Fixed forward in compositional metrics (Fix ComputationalMetric.forward() to not only consider the last batch #645)
