### Describe the goals of the changes to the analysis module.

We generated metaprograms on all Neuroblastoma samples in SCPCP000004 with `ews-nf`, which follows the same pipeline being implemented in `metafactory`. We want to create some initial figures that we can use to summarize these metaprograms.

### What will your pull request contain?

A script that reads in the metaprograms and outputs figures that might be helpful to show for this pilot group when presenting the `metafactory` workflow. The exact figures I want to make are TBD, but might include a heatmap of the top gene sets across each metaprogram, the correlation heatmap, and/or a UMAP of all neuroendocrine cells where cells are colored by metaprogram scores.
