[Feature Request] Count NAND gate usage, as well as other built-ins

[gardrek]

For those of us optimizing for circuit size / complexity, it'd be cool to have some sort of option that tells you how many NAND gates a circuit uses, as well as counting other built-ins, mainly the tri-state buffer. This could for instance be a toggle that shows this number similarly to the chip labels. Below is a mock up of this idea.

It could also be a toggle able overlay so while your are editing a chip it will display a gate count in like the top right corner

i made a rust program that does that for fun works pretty well
