/**
* This method is like `flatMap` except that it recursively flattens the
* mapped results up to `depth` times.
*
* @since 4.7.0
* @category Collection
* @param {Array|Object} collection The collection to iterate over.
* @param {Function} iteratee The function invoked per iteration.
* @param {number} [depth=1] The maximum recursion depth.
* @returns {Array} Returns the new flattened array.
* @see flatMap, flatMapDeep, flatten, flattenDeep, flattenDepth, map, mapKeys, mapValues
* @example
*
* function duplicate(n) {
* return [[[n, n]]]
* }
*
* flatMapDepth([1, 2], duplicate, 2)
* // => [[1, 1], [2, 2]]
