Can't change priority for files in torrent

[niks255]

I'm connecting to qBittorrent 4.2.5. When I change the priority of files in a torrent, it doesn't change.

For now, that option only works on qBittorrent 4.3.5 and above because older versions don't return file index when getting files. But we can create indexes manually for backward compatibility.
