This adds support for extracting the huge texture DLC PAK that you get in MH Wilds. Thanks to gibbed for figuring out the exact format change for that PAK variant.

I should note that REtool does not supporting extracting every single file from MH Wilds. I'll eventually get to updating REtool so it supports that, but it's low on my priority list since several other tools makers have made tools for extracting RE Engine PAKs.

Another thing to mention on the topic of MH Wilds: it's not possible to create PAK mods for the game since it has stronger PAK authentication compared to previous RE Engine titles.
