ENH: Allow to compute modulus and phase from 2 bands scalar image

Summary

The support of complex images in otb applications as improved in version 6.6. There is generic mechanism based on teh ClampImageFilter which allow to go from/to complex or multi-bands scalar images. The only change is to read the input image as ComplexFloatImageType which support both complex image (single band) or image with 2 bands which corresponds to the real and imaginary parts. The documentation of the application has been updated to reflect this modification.

Rationale

Allow to compute modulus and phase from complex single image and 2 bands as it is fully supported by otb filters

Implementation Details

Applications
