replicate array/inverter n times

[wholmgren]

We currently have an ability to duplicate an Array within an Inverter or to duplicate the entire Inverter layout.

It might be useful to have an option to replicate the Array or the Inverter by a given multiplier. We wouldn't necessarily need/want to show the replicated metadata and make it editable.

No one wants to hit the duplicate button tens of times for a tens-hundreds of MW scale system.

Maybe the solution is "don't use SPI to model your giant plant in that kind of detail" but I also don't think it would be that hard to support.
