Packet Events for v2

[casperwtf]

Hi, I noticed that the v2 for invui still depends on NMS, what are your thoughts on moving to packetevents for uis?

The licenses are incompatible, so using packetevents is not on the table and I haven't looked further into the library. Though, I would be curious to know how packetevents handles entirely incompatible protocol changes, such as the recent change to hashed item stacks. I would assume this would still require specialized handling in InvUI, diminishing the value of using a third party library (assuming your goal is multi-version support).
