Create a CLI client

The idea started with https://github.com/librespot-org/librespot-java/issues/67#issuecomment-479077488. I’d like to know from @elganzua124 and maybe @arifainchtein what kind of use they’ll make out of it. I’m not really sure if it needs to be a one time command or a command that, once started, will accept more requests from stdin.

@sJJdGG I’ve added the Player#load(String, boolean) method on branch new-spotify-api. You can use it by doing something like this:

Session s =  new Session.Builder(new FileConfiguration(args)).create();
s.player().load("" /* Context URI (track, album, artist, episode, ...) */, true /* Whether to start playing immediately*/);

@rafaelsgirao The interactive CLI module has been discontinued a long ago. You can have a look at what had been done here: https://github.com/librespot-org/librespot-java/pull/84
