[F-R] Save selected library filters across app restarts

[khonkhortisan]

open shosetsu open the filters menu enable a filter close shosetsu open shosetsu current behavior: no filters selected desired behavior: filter still selected

Having the filter set like this would, assuming I'm caught up on what I'm reading, show me new chapters first. FILTER: ☑ Unread status, SORT: v By unread chapter count

This is a feature that tachiyomi has that shosetsu lacks.

Surprisingly, Shosetsu does have the codebase for library filter saving. It seemed at some point it became detached.
