 * The same as [`each`]{@link module:Collections.each} but runs a maximum of `limit` async operations at a time.
 * @name eachLimit
 * @static
 * @memberOf module:Collections
 * @method
 * @see [async.each]{@link module:Collections.each}
 * @alias forEachLimit
 * @category Collection
 * @param {Array|Iterable|AsyncIterable|Object} coll - A collection to iterate over.
 * @param {number} limit - The maximum number of async operations at a time.
 * @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 `eachOfLimit`.
 * 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
