[0.10.10] Innacurate demand satisfaction with many grids

[pyrolytic_tungsten]

When multiple grids are involved displayed electric demand satisfaction may not be accurate.

This pole shows bad electric demand satisfaction:



The only load the Radar mk3 (mod item) shows that it is fully powered:


My gut says that this may take some work to fix so I wouldn't expect it in the 0.10.X branch.

Steps to reproduce:

1. Install and enable Advanced Radars (I wanted a large dummy load)
2. load this save.
3. Look at the electric demand satisfaction of various poles

I took a look at the save. And the similar could be reproduced with just two networks.

The problem is, that this is the implication of the way the electric network works. The energy networks are updated one by one.
The first network updated doesn't have enough energy to fill the radar buffer, so it is marked as red, the second one doesn't have enough energy as well, but the radar gained some energy from the first network already, so the info shows little bit more etc. until it is green for the rest of the networks.

I don't see a way to fix this behavior that would not bring extra performance drain, and I consider it to be not worth the trouble at this moment.
