Add iCloud sync for 115 cloud drive

The 115 cloud drive has a very low QPS limit, so it takes a long time to scan the content.
I have to scan it four times for my Mac, iPhone, iPad, and Apple TV.
If Infuse could save the scan results in iCloud and sync them across devices, it would make a big difference.

Also, if Infuse could prioritize scanning the most recently modified folders first, it would help display new TV shows and movies on the main page much faster.
