In addition to comparing the exposure levels of the sorted input images to determine whether a new exposure group must be created, this commit adds a detection based on the path of the image: if the directory containing the current image is not the same as the one of the previous image, then we assume the dataset is different, and there is no point in comparing the current image's exposure level with the previous one's. Instead, we directly create a new exposure group. In cases where images from different datasets have very similar exposure levels, this prevents having outliers identified as being part of the current exposure group.

I added a detection for new exposure groups based on the path of the images to correctly handle cases where the outlier(s) might have an exposure level that would be coherent with the current exposure group, thus causing an erroneous bracket detection.
For example, if an outlier's exposure level is (22.0, 10.6, 200) and it gets sorted before a dataset whose first image has an exposure level of (22.0, 10.2, 200), both images would be put into the same exposure group unless we use the path information that's available.

Bracket size selection is now tolerant to at most two spurious image in the images list.
rule : (Bracket size * countGroupsWithThisSize) >= totalImages - 2
