find_construction_networks_by_position

[mknejp]

There is already LuaSurface.find_logistic_network_by_position(position, force) but it obviously only works if you test for a position inside the orange zone.
It would be useful to have

LuaSurface.find_construction_networks_by_position(position, force) -> array of LuaLogisticNetwork

which finds the networks covering the given position with their green zone. It returns an array since construction zones can overlap without being connected.

Analogous LuaForce.find_construction_networks_by_position(position, surface) -> array of LuaLogisticNetwork
