Modified GlobalHistogramEqualization to use the ColorHistogram class
HistogramMatchingFilter should support color images now
ReplicationScalingFilter now supports color images
Optimized an edge case in BilinearInterpolationFilter
BinlinearInterpolationFilter supports color images
Fixed bugs in ReplicationScalingFilter.cs
Fixed the returned image in BitDepthModification.cs
Broke parts of bilinear scaling into separate functions

Right now it is broken and i'm not sure why :(
Fixed BilinearInterpolationScaling

I was casting non null pixels to bytes by accident
