[playlist-plugin] Add smart navigation

[jboix]

Description

As an integrator, I want to enhance the playlist plugin to include smart navigation capabilities, aligning the API with the behaviour found in Apple and Android libraries.

Acceptance Criteria

• When the user clicks the previous button, the behaviour should depend on the current media's playback position:
  • If the media is within a threshold of n seconds from the start, it will navigate to the previous item in the playlist.
  • If the media is beyond this threshold, it will restart the current media.
  • Live media always navigate to the previous item, regardless of the threshold.
• The threshold should be configurable, with a default value of 3 seconds.
