Reading the "real" player yaw in a Movement.

When in a Movement, how can I get the "real" yaw of the player.
In for ex. in MovementParkour.java how can I get the yaw of the player, that in the end gets send to the server?

`ctx.player().rotationYaw` only returns the players yaw, that is "on screen".
As well as `ctx.player().playerRotations()`.
`ILookBehavior` doesn't have a function to get the target rotation.

One could disable `freeLook` so the rotation is forced, but I still want the `freeLook` abililty.

## Final checklist
- [x] I know how to properly use check boxes
- [x] I have not used any OwO's or UwU's in this issue.
