mirror-yt: Update output name format 

We add the video height to the output file name if it's given.

We also add the playlist_index as a prefix, if the user requests this.
This is most likely a good idea, because videos uploaded on the same day
can otherwise be in another order than intended. This is most likely not
backwards compatible so already-downloaded channels should not use this.
