Display gene expression along a given reduced dimension on a heatmap

Inspired by (and using code from) t-SNE-Heatmaps from the Kluger Lab, this creates a heatmap visualizing gene expression along a given dimensional reductions coordinates. Unlike the example code given for t-SNE-Heatmaps, this works with any dimensional reduction (i.e. UMAP)

As an example, these are the marker genes (as determined by Seurat's FindAllMarkers() function, using MAST) for the cell types identified in the Villani et al. Science 2017 paper displayed along the first UMAP dimension: Villani plot

Currently works with Seurat 3 objects or a gene expression matrix.
