SmoothCoasters

Added support for Minecraft 1.17.1.

Adds camera rotation modes which can be configured by the server:

Camera (old, default): Only your camera is rotated, your yaw/pitch is not changed. You're not able to interact with the world while your camera is rotated because you're not actually looking in the right direction.

Player (new): Your yaw/pitch is changed in addition to the camera rotation. You can interact with the world normally. This mode has to be explicitly enabled by servers because the fast player rotation changes could cause problems with anti-cheats.

Allows servers to configure the interpolation ticks of an entity.
