PacketDump

Adds support for 1.21.9, 1.21.10, 1.21.11, 26.1, 26.1.1, 26.1.2 and 26.2.

Packet and field names now use Mojang names on every version, so they read the same no matter which version you run. On 1.21.8 that means you will see ClientboundSetHealthPacket where 1.0.0 showed HealthUpdateS2CPacket.
