Add animation rigging package (third times the charm) Add new Facepunch.BoneJobs plugin BoneJobs is a stripped down, simplified way of using Animation Rigging without having to use the cumbersome RigController (and espensive) rig handling system that the package depends on Currently only has a single component, the AimSpineComponent Instead of relying on a selection of loose rig controllers, this component does exactly what we need in a single place - adjust all of the spine bones to look at a given target with a variable rotation offset so we can account for 3/4 stance poses on a per weapon basis The advantage of still using the underlying tools in the Animation Rigging package is that the core math is really fast and runs in jobs so we can in theory move all of our IK and bone manipulation handling to threads It also has quite a bit of functionality we want and all of the math already done (quaternions are confusing), so next steps will be porting over some more components that we need
