Duplicated czi metadata

[K-Meech]

In the 'Filetypes and metadata' episode, we browse the metadata of the ‘Plate1-Blue-A-12-Scene-3-P3-F2-03.czi’ file. Under images, there appears to be two images Image:0 and Image:2 with nearly identical metadata. It would be good to provide some kind of explanation of these two sets of metadata, given that only one image is displayed in napari.
