Example of Shrink.map usage does not type

The signatures for `map` and `andMap` are

```
map : (a -> b) -> LazyList a -> LazyList b
andMap : LazyList a -> LazyList (a -> b) -> LazyList b
```

and the example shows them used as

```
type alias Vector =
{ x : Float
, y : Float
, z : Float
}

vector : Shrinker Vector
vector { x, y, z } =
Vector
|> map (float x)
|> andMap (float y)
|> andMap (float z)
```

So `map` is getting a `LazyList Float` as it's first argument and a `Float -> Float -> Float -> Vector` function as the second one. That's the revers of what the signature says.
