Additions

Added spec teleportation.
- /spec tp <player> [slashspec.teleport] — Allows you to teleport to another player while you are in spec. The other player can disable this if desired.
- /spec tptoggle [<enable/disable>] [<player> (for admins)] [slashspec.teleport.toggle[.others]] — Toggle whether other players are allowed to teleport to you (or another player, for admins). If disabled, other people will not be able to use /spec tp to teleport to you.
- Config option: teleportable-to-default: true. Sets whether players may be teleported to by other players by default.
Added spec combat tagging. Players will not be able to enter enter spec if they have recently been attacked by another player or if they have recently attacked another player. This is useful if players are abusing spec to escape combat situations. This will work for both melee and ranged attacks.
- Config option: combat-timer-seconds: 30. Controls the number of seconds after a player attacks another during which neither player may enter spec.

Changes

Spec fireworks (/spec firework) are no longer instant by default, spawning a flight duration 3 rocket instead.

Tested for Minecraft 1.20.2. Should work for 1.20.4.
