[Feature] Armor Stand improvements

[Tiefseetauchner]

Hi! I haven't seen an issue tracking armor stands being supported (like for armor stand art), I've run into this being an issue a lot recently with Hermitcraft, and I wanted to have some place where we can track what the current state is and so there can be discussion on how things are implemented so that there can be more collaboration

I wanted to ascertain what the current state of armor stands is, and what is needed to make them work correctly, so maybe I can work on it if it's wanted. A few things I think I want to track here:

• Arm visibility
• Arm/Leg/body/head rotation
• invisible armor stands
• items in hand
• Baseplate visibility
• Small Armor Stand
• player heads based on the actual in game texture, as one could have changed their skin to get different heads (might be tracked separately)

Feel free to close this issue if this is tracked elsewhere or is inappropriate
