feat: option to stack oscilloscope signals

[edwloef]

Before filing

• I searched existing issues for a duplicate.

Problem

I'd like to be able to overlay the side signal over the mid signal, in a different color

Proposed behavior

Add ability to put signals in a stack instead of a column, and add per-signal trace coloring

Additional context

No response

Good idea, that shouldn't be hard to do. I'll get something pushed today.

Let me know if that works for you. Channel 1 will render above channel 2.

Yup, works great :D thanks!
