Subject: [PATCH 1/2] Allow configuring ruin/empty space level count - #36191

Allows map configs to set how many ruin levels (def. 7) and how many empty levels (def. 1) that will be created. Most useful for landlocked stations, event/one-off stations with unusual composition, or testing situations such as RuntimeStation.
