1.3.1

This version is a hotfix release. It fixes the following issues:

• Some prediction algorithms might predict a binding affinity of 0 which could lead to division by 0 errors when calculating the fold change. In this situation we now set the fold change to inf (infinity).
• Previously the --maximum-transcript-support-level threshold was not getting propagated to the main pipeline step correctly, resulting in errors in the transcript support level filter.
• There was a bug in the multiprocessing logic that would result in certain steps getting executed more than once, which in turn would lead to FileNotFound errors when these duplicate executions were happening at the same time.
