Segmentation fault when compressing 16 bits RAW

[lizhihao6]

Hi, thanks for your great project,
I got the segmentation fault when I was converting a RAW image into 16bits compressed DNG.
Seems bug from 'pack16tolj'

            tile = pack16tolj(rawFrame, int(width*2),
                              int(length/2), bpp, 0, 0, 0, "", 6)

I don't have the time to look at this currently, but if you just need a working DNG; you can work around this by disabling compression.
