ChangeAllyShootPacket and ShootAckPacket have incorrect labels/ids

[tiffit]

ChangeAllyShootPacket (id: 122) contains only one int, 1 to enable and 0 to disable ShootAckPacket (id: 121) contains an int and a short, the int is the time and the short is the number of enemy shoots that are being ACKed.

I have no idea what packet 100 corresponds to (or if its any packet at all). I also do not believe "ShootAckCounterPacket" is a packet.

Big thanks. Will fix according to this.
