[Feature Request] Add tracking support

[taos15]

What feature should be added to Suwayomi?

Add tracking for anilist

Why/Project's Benefit/Existing Problem

It will allow user to keep reading history in sync

What should be included?

Tracking should have a toggle option for 2 way sync, updating to the highest chapter count. EX. local chapter read shows 150, anilist shows 160; if the toggle for 2-way sync is on, the tracking implementation will change local chapter to match anilist since it has more chapter reads. If it is not enable it will behave as push and only update anilist like current mihon implementation
