Description

The 4 subclasses of RasterModel.parse() 2D/3D images/labels, accept DataArray as arguments, but do not accept DataTree. For consistency we should add this option.

Until this is added, the recommended usage is to manually construct a DataTree and call .validate() on the appropriate model.

Research direction

Start by locating the four RasterModel.parse() subclasses for 2D and 3D images and labels, then compare their current DataArray handling with the DataTree validation path described in the issue. Done means each parse method accepts DataTree consistently, while the existing DataArray behavior remains supported.
