feature: timing diagram

See original GitHub issue

This is a feature Request for a new chart type “Timing Diagram”.

“A digital timing diagram is a representation of a set of signals in the time domain. A timing diagram can contain many rows, usually one of them being the clock. It is a tool that is commonly used in digital electronics, hardware debugging, and digital communications.” - via wikipedia

This chart type should support the following features:

x-axes: normal number but also timing-series.
y-axes can only have values false/true or 0/1.
The area underneath each “1” signal can be filled with a color (in red above).
every signal (y-axes) has a baseline (same as “0”) (in green above).
It should be possible to use this chart-type as a subplot.
series can have different names, colors …

I’m thinking of merging all new trace type request like this one in https://github.com/plotly/plotly.js/issues/2221 until we start work on them.

Sounds ok @alexcjohnson ?

I’ve seen plenty of charts like this with some of the signals analog. Wouldn’t need to be included from the outset but we shouldn’t preclude it.

This could of course be created already using one subplot and one trace for each signal, but I can see the argument for making it a single trace: it would have better performance, much cleaner API, and the interactions could be tailored to this use case.
