apps: common: dng_writer: Fix RAW10 and RAW12 packing on BE machines

The 16-bit padded raw 10 and raw 12 formats are stored in memory in little endian order, regardless of the machine's endianness. Read pixel data as uint8_t values and hardcode bit shifting to little endian to fix scanline packing.
