Retargeting MetaHuman Facial Mocap to Arkit Face Test

Issues:
- Amplified motion, Jittering are applied due to the photorealistic metahuman's small and delicate movements. In addition, other differences in facial features also have an impact.
➡ Can be modified via "modify curve"
- Limitations of Arkit's 52 targets(curves). Some expressions cannot be asymmetrical. Subtle facial expressions of metahumans not included in the 52 have disappeared.
- Unreal Engine crashes if the Anim Sequence Editor and Sequencer are launched simultaneously.
- The manual mapping process is cumbersome. A remapper function was introduced in version 5.7, and while related nodes exist, there is no related documents.
- To ultimately bake into ARKit controls, a backward structure must be built
