Added a CLI and the ability to download individual tracks.
I noticed that this was targeted at downloading playlists/the pages such as popular which had a lot of tracks. I've added a second python script, very similar to the first that can now be run and will accept the command line argument of the link of the track you'd like to download. This makes it possible to more quickly and efficiently download individual tracks. I've also added some ASCII art to signify when the track is finished downloading.
Something to note is that this still works to download multiple files at once. For reference, the above was this link and it downloaded both tracks on that page with a very simple input.
looks fine but it might warrant just calling the other scripts functions rather than duplicating. (making it more of a lib)
that way fixes don't need to be copied/pasta everywhere.
