/**
* The same as [`each`]{@link module:Collections.each} but runs only a single async operation at a time.
*
* Note, that unlike [`each`]{@link module:Collections.each}, this function applies iteratee to each item
* in series and therefore the iteratee functions will complete in order.
* @name eachSeries
* @static
* @memberOf module:Collections
* @method
* @see [async.each]{@link module:Collections.each}
* @alias forEachSeries
* @category Collection
* @param {Array|Iterable|AsyncIterable|Object} coll - A collection to iterate over.
* @param {AsyncFunction} iteratee - An async function to apply to each
* item in `coll`.
* The array index is not passed to the iteratee.
* If you need the index, use `eachOfSeries`.
* Invoked with (item, callback).
* @param {Function} [callback] - A callback which is called when all
* `iteratee` functions have finished, or an error occurs. Invoked with (err).
* @returns {Promise} a promise, if a callback is omitted
