Feature to migrate from Tachiyomi.

[LilithMorningstar666]

Describe your suggested feature

With the last pre released version I take the decision of fully migrate from Tachiyomi to Kotatsu, the problem, I have a lot of favourites and library custom categories. I want to suggest that add a migrate option to recover Tachiyomi library on Kotatsu will be a good feature. If library categories can't be recover but favourites can be recovered, it's fine.

Thanks for your work with Kotatsu, it's an amazing reader app. I can understand if this feature it's not planned or can't be added.
