++Grey-scale image as a MIPI RAW12 packed array
++
++
++Description
++===========
++
++This is a packed grey-scale image format with a depth of 12 bits per
++pixel. Two consecutive pixels are packed into 3 bytes. The first 2 bytes
++contain the 8 high order bits of the pixels, and the 3rd byte contains the 4
++least significants bits of each pixel, in the same order.
++
++**Byte Order.**
++Each cell is one byte.
