ENH: OTB-626: time range in PHR metadata are supported for Dimap v1 and v2, only used for SENSOR products

Co-occurrence Matrix computation using itkScalarImageToTexturesFilter has been replaced
using a different technique which reduces the computation time. This was used also in
ScalarImageToTexturesFilter class. Also number of iterations over the histogram
has been reduced to minimum and replaced with co-occurrence indexed list iteration
wherever possible. Maximum value of for grey level images was corrected to 255
in the Testing code.
