/**
* Creates a flattened array of values by running each element through iteratee and flattening the mapped results up to depth times.
*
* @template T, R
* @param collection - The array or object to iterate over.
* @param [iteratee] - The function that produces the new array elements.
* @param [depth=1] - The maximum recursion depth.
* @returns A new array that has been flattened up to the specified depth.
*
* @example
* flatMapDepth([1, 2, 3], n => [[n, n]], 2);
* // => [1, 1, 2, 2, 3, 3]
