    rotation="0" will lock the rotation to 0 or whatever other direction (0, 90, 180, 270)
    no_rotation=true just means "0"
    prevalence is how common it is, but avoid setting huge values
    skip_above=3 means it will place this schematic, and then the next 3 vertical segments will
        be skipped to prevent game from generating on top of previous ones
    vertical_segments is a list of positions that allow (1) or disallow (0) placing this schematic
        so if you have a basement schem, you set it to {1,0} and a ground floor would be {0,1} because
        you don't want basements spawning on the ground floor
