Handle any Vec size in VTKDataSetReader
The legacy VTK file reader previously only supported a specific set of Vec
lengths (i.e., 1, 2, 3, 4, 6, and 9). This is because a basic array
handle has to have the vec length compiled in. However, the new
ArrayHandleRuntimeVec feature is capable of reading in any vec-length
and can be leveraged to read in arbitrarily sized vectors in field
arrays.
