[Suggestion] Armor stand spectating login

[MithrandirCraft]

What feature do you want to see added?

Adding an optional feature that forces players which are either logging in or registring to spectate within an invisible armorstand, for 0 position and head pitch yaw movement.

Making the armorstand's XYZ EulerAngle's, as well as actually using this login approach or not, configurable.

The suggestion for this system was made by @krusic22 on the AuthMe Discord. But it is unlcear if it's actually feasible to be integrated into AuthMeReloaded.

I tried implementing this myself for a later PR, but found Authme's architecture quite daunting, and couldn't make my code fit properly. So I am now suggesting a more experienced dev to implement this instead.

Here's my initial approach to a class that would set up the Armor Stand for one: https://gist.github.com/MithrandirCraft/a0f2ec81c9e1ef0a9c95e962a66bd487

Are there any alternatives?

Yeah. AuthMe used to have a rather rudimentary head position rollback (I do not know if this is still in place), and also still has a position rollback, both of which are not too good at preventing both types of movements, but do indeed roll them back.

Anything else?
