Plot Observable(Pyramid) correctly

[felixcremer]

I would like to combine Observable and some data lazily, so that we can build dashboards on top of the Pyramid which would change the heatmap based on the values of some slider for example.
I can construct an Observable(Pyramid) but then the plotting would run into the DimArray fallback for plotting Observable(DimArray).

I am not sure, whether we would have to properly fix this by using the Makie recipe system properly instead of the dispatch on the Pyramid type on plot.

Looks like this is another case for not making Pyramids a DimArray

I don't think, that this is the underlying problem it is rather that we didn't properly implement a Makie recipe for the Pyramid. We simply run into the next best thing which is the DimArray fallback.
If Pyramid would not be a subtype of AbstractDimArray we would simply fail in some lower level Makie code.
