Two-way sync to mirror tracking services progress in app

[Lolen10]

Describe your suggested feature

Currently, the tracking sync feature operates in a one-way direction: from TachiyomiSY to the tracking services. By implementing a two-way sync (between TachiyomiSY and the tracking services), users can effortlessly synchronize their reading progress across multiple devices. An existing Tachiyomi fork already incorporates this functionality, which can be found at this link: https://github.com/Saud-97/TachiyomiS97.

Fuck TachiyomiS97. They are a crap fork who removed limiters that Tachiyomi added to be nice to sources.
