Type class for fixed length typed arrays. Takes another Type as input and produces an array type for it.
Usage:
const {ArrayType, T} = realm;
const NumberArray = new ArrayType(T.Float64);
const numbers = new NumberArray(3);
numbers[0] === 0;
numbers[1] === 0;
numbers[2] === 0;
numbers[1] = 123;
numbers.forEach(num => console.log(num));
