/**
* Removes elements from an array at specified indices and returns the removed elements.
*
* This function supports negative indices, which count from the end of the array.
*
* @template T
* @param arr - The array from which elements will be removed.
* @param indicesToRemove - An array of indices specifying the positions of elements to remove.
* @returns An array containing the elements that were removed from the original array.
*
* @example
* const numbers = [10, 20, 30, 40, 50];
* const removed = pullAt(numbers, [1, 3, 4]);
* console.log(removed); // [20, 40, 50]
* console.log(numbers); // [10, 30]
