DataSource can only read arrays of 1, 2, or 3 components

When reading vector data from an ADIOS file, it is only possible to read data that has 1, 2, or 3 components. This is because it creates a static ArrayHandle of some fixed sizes. See https://gitlab.kitware.com/vtk/fides/-/blob/master/fides/DataSource.cxx#L484.

Fides should use the newer ArrayHandleRuntimeVec to specify any sized vector at runtime.
