std::out_of_range when accessing SaveTrafficData object

[shmocz]

ServiceData objects are deinitialized in ExitGameLoop hook:

ra2yrcpp/src/hooks_yr.cpp

Lines 388 to 400 in 21491da

	DEFINE_HOOK(0x72dfb0, ExitGameLoop, 0x6) {
	(void)R;
	auto [mut, M] = MainData::acquire();
	GameCommandData::get()->game_state()->set_stage(
	ra2yrproto::ra2yr::STAGE_EXIT_GAME);
	M->deinitialize_service_datas();
	// Flush output in case the process is not terminated gracefully.
	std::cerr << std::flush;
	std::cout << std::flush;
	return 0U;
	}

However, calls to TunnelSendTo and TunnelRecvFrom are still happening, causing std::out_of_range to be thrown in the respective hooks.

Solution is to perform ServiceData deinitialization elsewhere when tunnel related recvs/sends are no longer occurring.
