Kernel is now compiled and linked into a raw binary instead of intel hex. This raw binary can be loaded into the correct address by the bootloader. I wanted this to be an o65 file, but ld65 kept complaining about it. Honestly though having this be a straight binary makes it easier to load, but we can't relocate it.
