/*
 * Cách dùng rất đơn giản, chỉ cần new 1 đối tượng picasa, truyền vào
 * tham số là link picasa ở 1 trong hai dạng, nếu link chết thì code
 * sẽ tự thoát, mình không có xử lý phần link chết.
 * Gọi hai hàm tương ứng để lấy link pm4.
 * Chú ý: Nếu chỉ có chất lượng 480 mà gọi hàm 720 thì nó vẫn ra 480
 * Dùng dạng feat=directlink dễ bị chết hơn dạng thứ 2.
