eBayes fails on dataset

[ppavlidis]

GSE272296

This dataset yields a prior dof that is infinite. It's a lower-quality data set (low effective library sizes), but I'm not sure why the algorithm is failing, investigation needed.

I'm considering this a bug for now, assuming we can make the algorithm work with this dataset. This should never fail or have a fallback to vanilla linear modelling. That can be done manually when running the DEA (-noBayes) but that's not a stable solution.
