add map_id condition for EoC

[GuardianDll]

Summary

None

Purpose of change

Another thing, tangentially requested by Karol for their mod, but would be useful anyway

Describe the solution

add map_terrain_id and map_furniture_id fields, that check is the coordinates they got contain specific terrain or not

Testing

Compiled, run EoC that is added in documentation

Additional context

The best approach would probably be using it in combination with foreach effect, so you just have a list of terrain to check and that's it
