 * @alias forEachOfLimit
 * @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 `key` is the item's key, or index in the case of an
 * array.
 * Invoked with (item, key, 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
