Would be useful if supported upgrades
can add
next_upgrade = "ownly_wind_turbine_mk"..math.min((level+1),3),
fast_replaceable_group = "wind_turbine",
to get upgrade planner to work using bots
but gets error "Unknown key: "entity-name:ownly_wind_turbine_collision_box_mk1" is in the way" for manual upgrade
