      programs. Fixes #1713.

    <change name="Kaitlyn Lee" date="2018-03-01">

      We were given a python program that reads in data from a ddd file

      to use as an example. In the python program, the way they calculate the

      number of bands is different from the one we previously used. The old

      formula did the number of total band bits / 8; the formula is now

      the (number of total band bits / 8) / the number of bytes of the data type

      of the file's bit type. ddd files are also pixel interleaved, so the program

      can now process files with multiple bands. Fixes #703.
