Tile latitude requirements
alienvalkyrie alienvalkyrie Minor problem: While at Tile range, a max latitude requirement can be emulated by a negated min latitude requirement, the same doesn't hold for other ranges; max latitude = "at least one tile in this range must be south of", negated min latitude = "all tiles in this range must be south of". Possible solutions:

Primitive solution: Only support Tile range for MinLatitude
I decided to go with that option. We can still expand to more ranges and add more variants (MaxLatitude, MinAbsLatitude perhaps?) when there's demand for it.

Introduce a "MinLatitude" requirement type at the Tile range to allow climate-specific effects. Latitude should be signed (positive/negative for northern/southern hemisphere) to allow seasonal effects (with year fragments).
