Implement Ether Surge #40

This calculator predates the Ether Surge feature, but it's kind of critical for any build order timing. It needs to be implemented in the calcuator for the calc to have any value at all.

This might just work as is based on how my code looks. Would be amusing if it did

For this to be more valid of a concept, I need to consider the node being harvested itself, not the thing doing the harvesting, as technically, using a Raw Surge is going to depleted future extractors, which isn't a concept I currently handle.

But that seems like future work and polish, I am going to be find with this bandaid for now, and do not refactor later
