Add more Fuzz functions for Array

There are multiple fuzzers for `List` that could benefit `Array` as well:
```elm
-- Based on listOfLength
arrayOfLength : Int -> Fuzzer a -> Fuzzer (Array a)

-- Based on listOfLengthBetween
arrayOfLengthBetween : Int -> Int -> Fuzzer a -> Fuzzer (Array a)

-- Based on shuffledList
shuffledArray : List a -> Fuzzer (Array a)
```
