`Array` contains three additional `Word`'s we do not need in `FlatBag`. Move
`FlatBag` to `SmallArray`.

Expand the API of SmallArray by `sizeofSmallArray` and add common
traversal functions, such as `mapSmallArray` and `foldMapSmallArray`.
Additionally, allow users to force the elements of a `SmallArray`
via `rnfSmallArray`.
