Remove cloneRotXYZ and replace accompanying tests with cloneTrot since this won't be used anymore

The best practice i've discovered is to compute the transformation matrix outside and pass it
to the hexagon. This is because usually we use the same transformation matrix not only to the hexagon but other things like legs or coordinate frames (axes). So we'll just compute the transformation matrix only once for all the objects that need it. This is why we don't need these kinds of abstractions anymore.
