Subject: [PATCH] Optimize Dynamic#get Missing Keys
get was calling toString() on every NBT object that was ever asked for an optional
key from the object to build a string for the error text.
When done on large NBT objects, this was using a ton of computation time building the
JSON representation of the NBT object.
Now we will just skip the value when 99.9999% of the time the text is never even printed.
