Add routes to the maltby Hub

Looking at the Maltby peripheral routes I think that there should be eight radiating routes from Maltby rather than the existing six.

At the moment, there needs to be a Dinnington - Tickhill route, however that takes a circuitous route via Langold.  So I think that there should be added a Maltby - Langold route. Which would mean that the periphery for Maltby  would be via Dinnington - Langold and Langold - Tickhill (which are already routes). This would be a better fit to fit the existing web.

I also think that there should also be a Maltby - Wadworth Route. Looking at Conisbrough and Wadworth there is a circuitous Conisbrough to Tickhill route, which goes virtually via Maltby at the moment. This would make the Maltby periphery Conisbrough - Wadworth and Wadworth Tickhill. That fits the existing web more  closely.
