Support for Hexen 64's file formats

[PerdGateEnjoyer]

Thanks to the efforts of Erick Vásquez, the IWAD used by Hexen's N64 port can now be extracted. However, the files are in a different format so as to be readable by the N64's architecture.

"The images are in raw format but have a 16-bit header that indicates the image size, xy offset and other parameters for the N64." -Erick

Erick's tool is able to create both an encoded and decoded version of the WAD (DecodeWadNormal and DecodeWadFormat respectively, tool included), so adding support for them should be a cinch.
