Does it work for more magical types like [ndarray](https://docs.rs/ndarray/0.15.3/ndarray/), which seems to use raw pointers?

For example, an Array2<u8> indeed uses https://docs.rs/ndarray/0.15.4/src/ndarray/data_repr.rs.html#21-25 which is:

pub struct OwnedRepr<A> {
    ptr: NonNull<A>,
    len: usize,
    capacity: usize,
}

For example, it can be as big as 10MB, but can deepsize recognize it?
