Universal colormap applicabillity #6897

Open jleibs opened 2 months ago

We have a nice configurable colormap component but at present you can only use it for DeltphImage and Tensors.

Any archetype that uses Color should be able to work with a scalar value and a colormap.

another motivation is size (see #6976):

When logging a lot of images, the data in rerun grows quickly. A lot of images are RGB heatmaps that stem from grayscale images. It would be nice being able to log images as grayscale and visualize them in rerun with a given heatmap.
