Reduces the values yielded from an async iterator

/**
 * @packageDocumentation
 *
 * Reduce the values of an (async)iterable to a single value.
 *
 * @example
 *
 * ```javascript
 * import reduce from 'it-reduce'
 *
 * // This can also be an iterator, generator, etc
 * const values = [0, 1, 2, 3, 4]
 *
 * const result = reduce(values, (acc, curr, index) => acc + curr, 0)
 *
 * console.info(result) // 10
 * ```
 *
 * Async sources must be awaited:
 *
 * ```javascript
 * import reduce from 'it-reduce'
 *
 * const values = async function * () {
 *   yield * [0, 1, 2, 3, 4]
 * }
 *
 * const result = await reduce(values(), (acc, curr, index) => acc + curr, 0)
 *
 * console.info(result) // 10
 * ```
