Changes the "Venomous Verdigris" mask to the PAYDAY 2 Retro Dallas mask.

Please note that the mask icon will conflict with other mods which change the mask UI icons, since they're almost all stored in the same file. There is also a few out of places pixels, but I've tried nearly everything to fix it and can't get it fully fixed. Luckily, they're barely noticeable. Enjoy!
