Add module for Progeny

[grst]

Progeny is a method for detecting enrichment of cancer pathways based on gene signatures

Input:

• sample sheet
• gene expression matrix

Output:

• Plot
• Table

I'm not sure if Progeny does proper statistical tests by group. If not, perform a simple statistical test, e.g. using a linear model.

Since it does not make sense to run Progeny on all datasets, this should be made optional (e.g. params.run_dorothea) and
be disabled by default.
