Feature request: categorial color scheme for cluster groups

[RvV1979]

Currently, colors indicating cluster groups represent a rainbow gradient across the loci. Consequently, when analyzing large gene clusters, neighboring genes have very similar colors. This can make it difficult to assess whether neighboring genes belong to the same group or not. See example below.

I would therefore suggest implementing an optional different color scheme optimized for categorical data such as, e.g. https://vega.github.io/vega/docs/schemes/#categorical

In addition, it would be great if genes and links could be labeled according to the group name for increased readability also for colorblind persons.
