As suspected, the rand-based RNG was causing many issues and has been replaced everywhere.

There were also logic error where putting a tile down was far too strict on the edges of the map.

Improvements

Terrain generation seems deterministic now
Terrain generator module is now more modular
New PNRG based on Wolfram's PNRG Rust implementation, as per MicropolisCore TODO recommendation.

Issues remaining

Changing the seed does not change the terrain output?
The terrain output looks weird and much less natural than when it used to work

Result (console output)
