Starter Content's "P_Explosion" does not successfully convert to a Niagara System - incorrect loop, spawn, sprite size, and collision behaviors

Starter Content's "P_Explosion" does not successfully convert to a Niagara System - incorrect loop, spawn, sprite size, and collision behaviors

Changes needed for / issues found with each emitter:

1. All Emitters 
   1. Emitter State - Loop Behavior: Once
2. Shockwave
   1. Color Over Life > Color
      1.  Alpha Curve is not correct - wrong key types, wrong shape
   2. Size By Life > Scale Sprite Size
      1. Curve's keys might need to be User and Auto (this is how they're set in Cascade) , but definitely not constant 
      2. Key tangents need to be adjusted
   3. Rotation Rate * Life > Sprite Rotation Rate
      1. Unsure - at least needs a curve somewhere, multiplying Particles.SpriteRotationRate by a float curve seems rightish? 
3. Fireball
   1. Size By Life > Scale Sprite Size
      1. Key at 0 needs to have a value of 1. Key at 1 needs to have a value of 3
4. Sparks
   1. Collision > MISSING 
      1. Needs collision module (w/ appropriate values), solve forces and velocity 
5. fire_light (doesn't look like it needs any changes)
6. Smoke
   1. Size By Life > Scale Sprite Size
      1. Key at 0 needs to have a value of 0.1. Key at 1 needs to have a value of 2

1. Open a project with Starter Content included, or import it to your project
2. Enable the Cascade To Niagara Converter plugin
3. Convert P_Explosion to a Niagara System
4. Place both systems in the level and compare

Result: The Niagara System does not look the same as the Cascade (multiple issues)
