Vanish No Packet

Updated for latest Minecraft (and only works on 1.16+)

Added support for PlaceholderAPI in faked join/quit messages.

Now preventing (some of these require using Paper):

Raid triggers

Natural mob spawns (including phantoms)

Collisions

Experience pickup

Arrow pickup

Frost walking

Entity interactions

Now supporting more containers for quietly observing.

Removed some oooooooold code.
