Function reduce

reduce<T, U>(accumulator: ((acc: T, next: U) => T), initial: T): ((arr: readonly U[]) => T)
Remarks
The initial value is mandatory. This is required so accumulator can accept different types for acc and next.

Example
```
import * as A from "flurp/array";

const concatWithLabel = A.reduce((acc, next) => acc + next, "reduced: ");
```
