Lots of changes, fixes and updates

First of all, this update uses PaperMC instead of base Spigot. If that poses a problem, I can try changing some stuff to make it work in Spigot servers. It has also been built for Java 17+, since older versions are not used anymore and they can always use the previous versions of the plugin.

• Fixed jukeboxes not stopping when they should and overlapping with themselves / the Minecraft disc
• Fixed music overlapping sometimes (except jukebox + other tracks)
• Fixed command (playhere? I don't remember the one that was doing something weird) arguments not working as described
• Added stop commands for both play/playhere and gplay. The gstop command only stops global tracks being played. The stopmidi command stops any tracks (not jukeboxes) being played for a player, including removing them from global ones
• Added support for target selectors
• Commands now use Mojang Brigadier system
• Song suggestions now take into account anything that has been written. Songs that start with whatever the command issuer wrote are shown before songs that contain the partial argument
• Imitating inserted disc effect seen when inserting vanilla discs
• Added rarity to disc config, and added said config to reload command
• When getting the disc of a song added after disc.yml has been generated, said file will be populated with the default values for that song (if it has not been already added manually)

I think that's all. I've tested it on my server, and it works perfectly. Please let me know if I made any mistakes. This is my first time using Brigadier.

I found an error in my PlayHere command, let me fix it before considering this.

Ok, PlayHere now works like a floating, invisible, intangible jukebox.
I've also added PlayLocation and some more stop MIDI commands.
