# note: A sub-image Huffman code with lengths 1, 2, 2, 2, which
#   over-subscribes the tree.
# expect: reject
# exercises: The same defect as codelen-oversubscribed, one level down:
#   BuildHuffmanTable() fails inside the predictor sub-image, and the
#   failure has to travel back out through DecodeImageStream() and
#   ReadTransform() rather than being noticed at the top.
