Hello, is this PR still a WIP? Or should we close it and open a new one changing the way the command nf-core licenses works? As you discussed in #1712

Gulp this is an old one. The question in the linked issue seems to remain unanswered. Also, it is commented out code and as such should in my opinion not be merged. Only if there is a resolution about how to treat/retrieve the license information and the code becomes useful should it enter the repo. It was a bit of an exploration and experimentation and I currently don't have the capacity to work on this. In the current state this PR merely serves as a reminder that there is code to either remove or reactivate.
