Gene set analysis

[pinin4fjords]

Description of feature

Probably a basic part of any differential analysis (particularly in expression) is a gene set analysis. I propose we have a module for the Broad's GSEA if it's feasible.

Module-level issue nf-core/modules#2584.

Adding GSEA to Bioconda at bioconda/bioconda-recipes#38167 (was a bit a surprised it wasn't there already, but there you go).

One could also think about:

• GSVA
• PLAGE
• SingScore

@apeltzer Absolutely - could I persuade you to create issues for each? GSEA will suffice for the MVP I think, and will establish the interface we can hopefully repurpose for the others.

GSEA module now merged from nf-core/modules#2617

Two additional adapter modules added to generate the correct matrix and class file formats.
