SegmentationDisplay.jl file, custom texture names can result in errors

[divingdiv]

If you pass a texture spec with name set to

"CTIm"
then the tuple inside of the tupleVectorData= should also be the same
("CTIm", voxelData)

This issue as well as correct type; defoult min max as min max present in array should be resolved by higher order function that accept Medimage; as well checked in appropriate assertions .
