Description
The restructure plugins maintain existing color tables, but the code needs to make some assumptions, because `Dataset` currently keeps its per-plane color tables in a separate data structure from the `ImgPlus` itself.
More generally, things like `Views` cannot properly preserve per-plane metadata since there is no such thing at the moment. (We have per-_axis_ metadata, but not per-plane.)
Ultimately, we probably need something like `AnnotatedSpace` but for intervals, so that each position of the interval can have some `Metadata`... although that would be per-_pixel_ metadata if implemented naively. To handle it per-_plane_ in a general way will require further consideration...

Research direction
Start by reading the Dataset and ImgPlus handling in the restructure plugins, then inspect how Views preserve axis metadata and how AnnotatedSpace represents metadata. Compare these existing structures with the issue's per-plane metadata requirement and determine a suitable interval-level design; done means the model can preserve per-plane metadata without the current separate color-table assumptions.
