[VFX] - DJ Sona Lightshow

My journey to learn VFX editing has led to to this case study. Behold, the culmination of implementing my research into one emote... still far from perfect, though. I'll get to custom animations eventually.

========================================

Adds DJ Sona's skin spotlight concert to /songbird.
Song: https://www.youtube.com/watch?v=SqlBX1sOcZI

You are free to port a custom animation onto it, be my guest, just link back to this mod.
( That's on my bucket list to learn but I wanted to release this early )

(The red flames during Concussive mode are 50% smaller now so you can actually SEE yourself but I'm too lazy to redo preview img/vid, just trust me that it looks better now)

========================================

Known issues:
- Most VFXs will not loop even though the song will. You have to restart /songbird to play the full lightshow again.
- The camerashake beats aint perfect. You try doing math with timing and see! It's some bullshit!

Tip:
If you have an issue with motion sickness, you can go into Advanced Settings and purposely remove or mess up the paths for "vfx/camera/eff/camerashake1.avfx" (there are 3 camera files total) so it no longer finds the files.
