Prints the offset of a given spotify track URI in a given playlist
Useful to find the offset to use to continue processing a large partially processed playlist because Spotify API tokens are only valid for 1 hour and some playlists with several thousand tracks take longer than that to process eg. spotify_playlist_tracks_uri_in_year.sh)
Playlist can be given as a name or id
URI must be in the form of spotify:track:uri as this is the native format in the playlist we are looking for
