Fixed Save States, Added a new "Save State per Frame" test, and other various improvements (#332)
* Made a simple headless example with it working for playing a game * Added another comment * Can't get any visuals from the core for some reason... * Fixed save states for WasmBoy Sound should no longer break save states, and tobutobu can be save and loaded during the intro * Left a TODO for before we push up fixes for demo` * Updated AssemblyScript * Fixed up all the tests, and allowed passing timeout to runWasmExport * Fixed Out of Memory errors on build * Added terser for the debugger for OOM errors
