Option to manually sync resume points

Resume points - option to manually sync

Expected Behavior

When syncing items from a library that are already part-watched, the resume point should be sync'd to Trakt as well.

Current Behavior

Currently, if resume points are deleted from Trakt (via https://sharkykh.github.io/tppm/) they are not sync'd back to Trakt by Kodi.

Possible Solution

This should be implemented as another toggle in the add-on sync settings, enabling us to use it in either or both directions and deciding which set of data (Kodi or Trakt) should be prioritised in a conflict.

Steps to Reproduce (for bugs)

1. Disable trakt add-on scrobbling (to mimic when a resume point is pre-existing in Kodi)
2. Part watch something to create a resume point in Kodi and confirm this exists by attempting to play back the same title.
3. Manually run a sync with the Trakt plugin.
4. Check the resume point via https://sharkykh.github.io/tppm/
5. Resume point for the item watched is not added.

Context

Somehow my resume points in Trakt were deleted one day when I had to resync my library to Trakt. I cannot figure out how to export these out to Trakt again from Kodi.
