Shift + I to hide/show all user's buttons updates buttons for all users

[mkapal]

When a user presses Shift + I, all buttons are cleared from their screen. When they press Shift + I again, all buttons become visible again for that user.

The Shift + I state is tracked by a single state shouldClearAllButtons in the global InSimContextProvider:

react-node-insim/src/lib/internals/InSimContext.tsx

Lines 41 to 64 in 7b2a50e

	const [shouldClearAllButtons, setShouldClearAllButtons] = useState(false);
	const [isConnected, setIsConnected] = useState(false);
	useEffect(() => {
	const bfnListener = (packet: IS_BFN) => {
	if (packet.SubT === ButtonFunction.BFN_USER_CLEAR) {
	log('User cleared all buttons');
	setShouldClearAllButtons(true);
	return;
	}
	if (packet.SubT === ButtonFunction.BFN_REQUEST) {
	log('User requested to show all buttons');
	setShouldClearAllButtons(false);
	return;
	}
	};
	inSim.on(PacketType.ISP_BFN, bfnListener);
	return () => {
	inSim.off(PacketType.ISP_BFN, bfnListener);
	};
	}, []);

This means that if one player restores their buttons, not only their buttons are shown again, but everyone else's buttons get shown as well if they has been hidden before.

Proposal: Keep track of the UCIDs which have requested to clear all buttons and when buttons are requested to be shown again, only show buttons for that UCID.

Buttons with UCID 255 need to be considered as well. When someone presses Shift + I, all global buttons should be hidden only for the UCID which has cleared the buttons and not for others. This means those buttons will have to be represented by multiple IS_BTN packets for each UCID that still has them shown.
