Revert back to react-photo-album and improve FolderGallery

MUI ImageList loads images one after another, which leads to loading all
 images even with loading=lazy. Maybe it depends on the order in which
 images are loaded, but this issue never arose with react-photo-album

FolderGallery always displays folder icons in the same way and simply
 positions the image to cover the space available. This circumvents the
 issue of different aspect ratios of images.
