Increase max ratio

Older versions of the game, and creative mode, send itemstacks to the server
when dealing with itemstacks, annoying, the compression algo used is good at
backreferencing, which means that compressed data can balloon pretty well.

64 should more than cover most cases of legit data, we could probably be more
harsh here, but this is likely a fine balance between avoiding bombs and not
erring out on legit data.
