Details:
When the whole data set is negative (due to some prior analysis for example
when the image is inverted), NoiseChisel isn't able to find any
pseudo-detections. This is because it doesn't so sky subtraction in the
pseudo-detection S/N measurement step. To fix this problem, I am busy
implementing sky subtraction in that step now.
This bug was found while testing on a dataset given by Gaspar Galaz.
