Invalid HeldItemSlot packet packets

Version
Minecraft Version: 1.20.4
MouseWheelie Version: 1.13.3

Describe the bug
When using the refill feature of MouseWheelie in multiplayer, the mod can trigger false positives for invalid held item slot packets with certain anti-cheat systems such as Polar AntiCheat and Vulcan AntiCheat. A specific scenario that consistently reproduces this issue involves having food (for example: golden carrots) in the off-hand and fireworks in hotbar slots 1 and 2. Upon depleting the fireworks in slot 1 through use, MouseWheelie automatically moves the golden carrots from the off-hand to slot 1 and switches the active hotbar selection to slot 2, which still contains fireworks. This action results in the player being flagged and potentially banned for suspicious game protocol by Polar AntiCheat and for bad packets by Vulcan AntiCheat.

To Reproduce
Steps to reproduce the behavior:

• Equip food in your off-hand.
• Place fireworks in hotbar slots 1 and 2.
• Use all fireworks in slot 1 to trigger the refill feature of MouseWheelie.
• Observe that the golden carrots are moved to slot 1 and the active hotbar selection switches to slot 2 simultaneously.
• The described action triggers anti-cheat systems, leading to flags or bans.

Expected behavior
The expected behavior is that the refill feature of MouseWheelie would not cause false positives with anti-cheat systems. Players should be able to use the mod's functionality without risk of being flagged or banned for invalid packet behavior. The mod should avoid making simultaneous item switches that are likely to be flagged by anti-cheat systems.

Additional context
This issue may not be limited to the specific scenario described and could potentially occur in other situations where the refill feature is used. Disabling "Refill on other occasions" seems to be a temporary fix for that problem.
