Total maximum power requirement reading

Add a stat to the power network readout showing total power requirement of all buildings on the network, (this would either be separate from or included in the energy production readout).
This would make it easy to understand how much power is needed to run everything at once, not just for what is currently be used.

I'm aware if you have too much on the network it just slows production rates, this however would let us know just how much power required to maintain maximum production across all machines.

One way I can think to implement this is to use the same power consumption stats from the crafting menu tab
E.g. 12 MK1 threshers(@400kw each) + 20 planters(@200kw each) = 8800kw total requirement, + 6 MK2 mining drills(@2400kw each) = 23200kw total power requirement.
