Add queue songs limit

[AlexInCube]

I suggest adding a queue limit so that people can't quickly use the entire memory of the bot by sending it huge playlists. For example, distube.options will have defaultSongsLimit parameter: 2000, but the queue itself will also have setSongsLimit() method. And when the queue tries to overflow, the SongsLimitReached event will be called, to be able to send a message to the user about the reached limit

Manage it yourself :/ <Queue>.songs is not private.

At what stage I need to edit the queue? at events addSong and addList?

It is up to you. Just put your code where you want to make it works.
