Vectorization on unstructured grids for different quadrature_permutations
Make it possible to vectorize SumfactKernels with different quadrature_permutation. Some notes:
- Ajust parallel_key
- The quadrature_permutation method of VectorSumfactKernelInput/Output should probably raise a RuntimeError
- The interface methods need to be adjusted. They should handle this in an upper/lower fashion.
