Improper __delitem__ definition in TAG_Int_Array

[sbliven]

Similar to #64, the delitem in TAG_Int_Array has an extra parameter. This causes Exceptions with pop() and remove().

Thanks!

If you have a small code snippet that failed, I'll make a test case to make sure this type of bug does not resurface.

The problem should surface when calling pop() on any TAG_int_array:

int_array.pop(0)

Specifically, I came across it when writing a script to reorder my server.dat file:

import os
from nbt import nbt
mcserverdat = os.path.expanduser("~/Library/Application Support/minecraft/servers.dat")
nbtfile = nbt.NBTFile(buffer=open(mcserverdat))
nbtfile["servers"].pop(0)
