Version: lostcities-1.16-4.0.9-beta
There are two generations I would like to request which is a toggle on or off inside the lostcity-server.toml. Like how bridges support/bridge generation etc can be toggled off.

1. Filler generation: Filler fills the border of each chunk below underground if there is a basement/cellar exists, but sometimes for multi-building designs they are interconnected to each other, the filler completely cut off their connection between cellars causing the cellar designs must be isolated from each other.

2. Door generation: Door (Including arch provided from the filler) generates based on if there is a part on any side of the buildings, this cause some frustration on my building designs since they always generate whenever there is a building near each other, including streets (building_front). Setting the building_front generate to 0.0 does solve the issue but it brings to another problem where building front doesn't generate now. Linked to: #395
