…re cropped in `extract_outlier_frames`.

This commit fixes a bug that introduces a mismatch between label-coordinates and video, when extracting cropped outlier frames.

When the `analyze_videos` step was performed using a cropping window. The predicted keypoints are stored in the crop-window space. In the previous implementation, the keypoints are ALWAYS converted back to reflect full-video coordinates by adding the left and top crop margins (introduced in PR DeepLabCut#2538). However the keypoints should only be converted back if the output frames are full-video, not when they are cropped. This commit fixes that by using the difference between the output margin and the margin stored in metadata.

* Fix unintended keypoint conversion to full-frame when output frames are cropped in `extract_outlier_frames`.
