RSDKv2 Decompilation: Retro Engine v2

RSDKv2 Decompilation is a decompilation of Retro Engine v2, the engine used by the 2008 Sonic Nexus demo. The README adds a built-in mod loader, a settings.ini file, and debug keys, and it builds with CMake. Running it requires Sonic Nexus 2008 demo assets, which are left out of the repository.
