Spawn blocks/structures/entities in biome dictionary tag or temperature

Status
Resolved
Issue description

We should be able to define custom biome tags to enable cross compatibility with other mods and easier generation based on temperature/biome type.

Issue comments

Adding new biome dictionary types is a bit out of scope at the moment, but I might consider this later down the road.

No, not adding new biome dictionary types.  We should be able to define spawning in existing types such as FOREST, MAGICAL, and DESERT
