Since the --memory and --scratchsize arguments are parsed with human-readable suffixes into bytes (e.g 2048MB or 2GB), if a user does not put a suffix the arguments are parsed as bytes which can cause issues later when a user sets the memory to be 2048 assuming it will be parsed as MB.
Change the documentation to match reality and also add a warning if the user has set either parameter less than the recommended default.
