Optimize restore backup

[xdeiimoss]

Describe your suggested feature

Usually Komikku (as well as most of other forks) takes at least 50 minutes to restore a backup. J2K and their forks takes 10 minutes maximum. The reason for that is SAF (at least that is what someone from the mihon discord server told me)

What they explained is: "But basically, the idea is, because SAF is really slow, you want to make SAF calls as less as possible. Such as use one call to retrieve all metadata you need for files under a directory instead of doing them one by one."

Also, tyvm for opening the issues tab! I appreciate it.
