You *can* use a byte array to write the scanline of a 16-bit image, but of
course in that case, the values written in the 16-bit image will only range from
0 to 255, and not the full 16 bit dynamic (GDAL will not automatically rescale
from 0-255 to 0-32767)

If you want to write values covering the full 16 bit dynamic, you will have to
use a short array and use GDT_Int16 in the RasterIO() call.
