Subject: [PATCH] Added support for the new "August 3rd" BIOS

There's a new BIOS revision floating around (MD5 hash first posted in Discord on August 3rd); no official announcement from Data Frog about it yet, but I've gone ahead and added support for it to the Boot Logo Changer and the Button Mapping Changer tools
