Fix issue where duplicate Huds can occur if they are added too quickly

[Zailer43]

Currently, Huds are bugged if added too rapidly. For instance, in the test mode, if J key is held down, Hud#add can be called twice because it triggers before ClientRenderCallback#BEFORE, resulting in multiple additions. Removing these Huds does not clear previous ones, making it impossible to remove the Hud

	ClientTickEvents.END_CLIENT_TICK.register(client -> {
	while (binding.wasPressed()) {
	if (Hud.hasComponent(hudComponentId)) {
	Hud.remove(hudComponentId);
	} else {
	Hud.add(hudComponentId, hudComponent);
	}
	}

I appreciate the effort in trying to fix this specific problem, but I think it's more fixing a symptom and less a problem - the entire implementation of this class if flawed and needs to be redone, which I'll take care of eventually.

As such, I'll be closing the PR - thanks for pointing this out though!
Cheers
