Add Cell Count to SubCluster Morpheus Heatmap

[gwaybio]

in #25 I performed a subcluster analysis to identify differential features across mutant and wild-type clones in each cluster independently.

There is one large big red cluster in the heatmap. We noticed that random example images from this block had high confluence (see below).

To more systematically address this question, I will add cell count to morpheus heatmaps.

Cells in Big Red Cluster

WT Clones in Well C02

Mut Clones in Well B06

WT Parental Clones in D11

Cells not in big red cluster

Mut Clones in D09

WT Clones in E05
