Audi R8 light config 2.1

Dynamic lumirank improved to show all three digits

- Tweaked the light cones for endulights ( middle one was way too bright )
- Increased glow power of led_stripes as their default texture is darker since 2.0

PS : I hope this is somewhat of a final version ! Sorry for the inconvenience

Description updated

Fix the high specular when lumirank gets in direct light.
