rustro_arch

Fixed a segault getting system directory, needed to be a CString

Started trying to get more cores to work without segfaulting but looks like I will need to refactor the code to use CString instead of String when passing data to cores

Now displays ARGB8888 pixel buffers correctly and shows the interface for 2048

Now supports variable framerate depending on the core

Merge branch 'main' of github.com:RetroGameDeveloper/rustro_arch into main
