Efficient wasm-implementation of an n-dimensional Array for Javascript

Wasm restrictions on Rust (at least at wasm boundary):

• No generics
• No polymorphims (no traits)
• No lifetimes

Solutions:

• no generics => enum NdarrayUnion for different type parameters for Ndarray
• no polymorphism => enum Subview for different behavior of ndarrays
• no lifetimes => Using if reference counting (std::rc::Rc), unsafe

Using enums requires minimally more memory (2 enums = 2 Byte)
