ZonalStatistics app inbv parameter is not taken into account in stats filter

Description

ZonalStatistics app does not filter out nodata value set through the inbv parameter.

Steps to reproduce

See: https://gitlab.orfeo-toolbox.org/orfeotoolbox/otb/blob/develop/Modules/Filtering/Statistics/include/otbStreamingStatisticsMapFromLabelImageFilter.h#L100

And implementation of UpdateValue:

https://gitlab.orfeo-toolbox.org/orfeotoolbox/otb/blob/develop/Modules/Filtering/Statistics/include/otbStreamingStatisticsMapFromLabelImageFilter.h#L126

In case a nodata is found, the count of pixel is not incremented but remaining stats are.

I have a patch for that (see upcoming MR).

It would be better to update filter test to also test the nodata case.
