plotAbundanceDensity colors

[antagomir]

The plotAbundanceDensity function currently allows coloring the points by a colData variable:

library(miaViz)
library(miaTime)
data("hitchip1006", package="miaTime")
tse <- hitchip1006
plotAbundanceDensity(tse)

Sometimes we need to map colors of the features (not points) to other external figures that use the same color coding for those features. For this it would be useful if we could also have a custom color for each visualized features (i.e. the rows in the above jitter plot). Something like:

plotAbundanceDensity(tse, assay.type = "relabundance", color_features_by=brewer.pal(n=nrow(tse)))

Sometimes it would be useful to color
