Vectorization strategy alters quadrature size
Implements the possibility, that a vectorization strategy alters quadrature order.
This is only actually done if vectorize_diagonal
and vectorize_allow_quadrature_changes
are set.
In the future, this will become more important, as it is needed for !189 (merged), but already very useful for !202 (merged)
