Decided to remove RAM snapshot function
Decided to remove RAM snapshot function

It can be implemented by using other public functions already on the
apu (namely read_u8), and I think it's better to provide a smaller
interface. Perhaps I end up bringing this back, but for now I'd like to
remove it.
