UMAPs without mitochondria #1

⚠️ This is stacked on the initiate-tumor-purity-module branch which has an open PR into OpenPBTA here: AlexsLemonade#1622 (stacked b/c this consumes results from that PR).

This PR explores dimension reduction without including mitochondrial genes, as inspired by this issue: AlexsLemonade#1601

There are two main changes here:

  1. I updated the transcriptomic-dimension-reduction module to include an option to remove mitochondrial genes. I added this run for stranded RSEM with log2 on in order to generate data for this exploration.
  2. I added a notebook to transcriptomic-dimension-reduction to explore the mitochondrial expression, first via just looking at FPKMs of mito genes for relevant diagnoses and then via UMAPs made with and without mitochondrial genes. I don't see anything too different here, but welcome thoughts on interpretation. Here's that notebook:

Since this is in my fork I can't quite request reviewers so I will tag @jashapiro and @jaclyn-taroni.
Edit - y'all have been invited so I can eventually request you, so there can be a bit more careful branch protection here.

After further conversation we're going to wait on this to merge into the main repo, so I'll close this.
