Support Motion JPEG
This change uses the default Huffman tables when a JPEG image does not have DHT markers. When a Motion JPEG frame does not have DHT markers, it assumes a decoder uses the huffman tables suggested by the JPEG standard. Even though it is not compliant with the JPEG standard, it is useful to support such Motion JPEG because it is used by many webcams.
