Compatibility With missing limbs features.

Idk a good tittle for that but anyways.

Some mods has "hide" limbs feature.. and would be cool to have some client config to turn on or off the check for "vanilla player parts visibility"
I'm suggesting this because there's a mod called pain prototype that has such feature and seeing that feature not working kinda break the immersion...

首先定位对 vanilla player-parts 可见性的检查，以及客户端配置的处理逻辑。对比 Pain Prototype mod 所描述的行为，然后定义配置开启和关闭时的行为。当 missing-limbs 功能能够根据客户端设置隐藏或显示 vanilla player-parts 时，即表示完成。
