Move image pixel reads to get_flattened_data and add the font libraries
Pillow 12 renames Image.getdata to get_flattened_data; the award image
normaliser and the isslop hue histogram both read pixels that way. The image
stack also needs pango, harfbuzz, fontconfig and a base font in the container,
so text rendering has glyphs to work with.
