This test code will run a WaveletImageFilter on given input image. Output
from this filter is then fed to WaveletInverseImageFilter which does
the inverse transform. Hence output of inverse transform passed to
ImageFileWriter will result in the input image.
Wavelet operator used is HAAR (otb::Wavelet::HAAR).
This filter works only in single-threaded setup
