Evergreen

Changes:

• Reworked Swamp trees, no visible changes but they generate faster.
• Reworked Spruce trees, no visible changes but they generate slightly faster.
  • Not entirely sure why as of right now but updating to Distant Horizons 2.2 cut the average generation time from ~40ms down to about ~10ms.
• Mangrove swamps and jungles won't be getting reworks right now since their generation speeds aren't too bad.

Upcoming:

• More optimizations.
• New tree types are most likely on hold until I get the world generation speed under control.
