The ability to start a download from a certain playlist position.

So I mainly use spotify dl for a personal playlist I have and as time goes on that playlist changes, it'd be nice to be able to start spotify dl from a certain playlist location so I don't have to spend extra time downloading the whole playlist and then getting the songs I want, downnloading each individual song or making a new playlist for songs.

I suggest adding an -O (--offset) option.
Something like -O 2 would start from the third song. Will work on implementing this right now.
