Monster Hunter Riders

There is simple xor on header part of model and atlas bundles (the rest is not encrypted). Key is dynamic for every file, probably derived from some hash, but I didn't dig into that. Here is workaround, which should work fine too. Tested on a few assets from 2.03 version of the game.
