1-Pin to multiple button assignment

This would allow even more crazy ideas.

This is basically a macro function, which currently isn't a planned feature. One concern is that macros are not tournament legal, so if this feature were to be implemented there would need to be a way to disable via a tournament mode option.

Going to keep this request open for now to see if there's a demand for this feature.

My apologies for not knowing the tech enough, but it's my understanding that the RP2040 has 3 analog inputs with 12 bit logic. This should be enough to build a resistor ladder with all the common controls.

I'm sure there is a huge gotcha I'm not thinking about.
