No metadata for each page from another multipage TIFF

Might be a duplicate of #223, however they didn't attach their sample file for regression tests etc.

This file was produced manually with tiffcp (libtiff 3.8.2, GnuWin32 port) from three images. Windows Photo Viewer shows every page. tiffinfo reports:

But, when using the recent metadata-extractor 2.19, an MWE similar to one in that issue,

       Metadata m = ImageMetadataReader.readMetadata(new File("color-pages-jpg.tif"));
       for (Directory d : m.getDirectories()) {
            for (Tag t : d.getTags()) {
                System.out.println(t);
            }
        }

reveals only a single IFD0 (the first page) plus a single thumbnail (the third page):

The file is for a particular corner case: I need an efficient (metadata-based) way to detect that there are multiple pages and their dimensions differ.

Thanks for the clear report and sample image. This looks shovel-ready for someone to pick up.
