Register Proliferation gene set

[GWMcElfresh]

Hi folks,

Small PR to curate some gene sets we're interested in quantifying in different aspects of this function: bimberlabinternal/Rdiscvr#71

I've named them such that it's clear that they're mostly meant to be used as a list of genes rather than a module. (by prepending Quantify.PctPositive).

A departure from the rest of the gene sets is that I'm seeking to collapse species differences in the same gene set (e.g. include both rhesus FCGR3 and also human FCGR3A).

Happy to drop in more gene sets if interested.

Talk soon!

Ben had a good point: we can register these in Rdiscvr directly, so we'll do that instead. However, this is still a good spot for the proliferation gene set.

Since we'll be adding gene sets in Rdiscvr, we need to export RegisterGeneSets() so the builds finish without raising warnings.
