Segmentation fault in dcmimgle when using LUTs >= 32bit

Description
Lines like const unsigned long ocnt = OFstatic_cast(unsigned long, inter->getAbsMaxRange()); in DiMonoOutputPixelTemplate (dcmtk/dcmimgle/dimoopxt.h) limit the number of LUT entries to what is representable by an unsigned long (Uint32 in most cases). These lines should be identified and changed to size_t instead.

I don't think that changing the data type is a proper solution to this issue. An array with more than 4.2 billion entries is certainly not desirable - at least not for optimization purposes.
