2.4-1.21.1

Effective 2.4 (Alpha) - 1.21.1:

As Effective is getting updated to 1.21 and beyond, the mod will move away from Lodestone to instead use Veil. As a result it requires a big rewrite, and instead of doing one big update, I figured I would do multiple alpha releases as I gradually work on it.

Replaced the Lodestone library with the Veil library
All the visual effects using Lodestone have been temporarily disabled until they get rewritten to use Veil. Temporarily removed:
- Chorus petals
- Will o' Wisps
- Allay trails
- Improved flames
- Improved dragon breath
- Underwater chest bubbles
- Waterfall clouds and mist
- Fireflies
- All screenshake effects
Rewrote splashes and glow splashes
Fixed inconsistencies with droplets sometimes appearing too far from the splash
