Using some header information from rom_tool, it was possible to implement something that will accurately determine the real ROM size. With that information, uncart no longer dumps in 2GB chunks, but to the actual size of ROM (all 8 partitions). Warnings were cleaned up as much as possible for now (2 remain). i2c support was added in order to be able to shut down uncart when it is over (it isn't clear that the ASM in start.s is right for returning control to brahma, if that's even possible). More warnings were enabled in the Makefile, and lto was enabled. Currently, the Makefile and the draw.h are configured for a9lh support.
