Seasonal Integration

• Allowed river biomes from River Redux and Climate Rivers to spawn pike, flowering rushes and pickerel✨ from Upgrade Aquatic.
• Updated ecliptic seasons integration to include tags for biome colours.
  • This makes jungle biomes, desert biomes and the pale garden have stable colours that don't change between seasons.
  • This also makes savanna biomes have moonsoonal colours, meaning their colours only change between the wet season and the dry season.
  • This also makes swamp biomes have much more subtle colour changes between seasons.
  • Finally, this makes badlands biomes have colour changes more suited for hot biomes and makes icy and snowy biomes have colour changes more suited for cold biomes.
