FImageCore::ProcessLinearPixels

ProcessLinearPixels act on image pixels as TArrayView64 Colors pass a lambda that is : ProcessLinearPixelsAction ProcessPixels(TArrayView64 Colors) return [ProcessLinearPixelsAction::Modified](API\Runtime\ImageCore\FImageCore__ProcessLinearPixelsA-) if you modify colors return [ProcessLinearPixelsAction::ReadOnly](API\Runtime\ImageCore\FImageCore__ProcessLinearPixelsA-) if you only read and don't change colors your lambda will be called on one row at a time
