Digital value enhancement

While the digital signal capability of LinePlot is nice, it would be very cool to have a more powerful version of it to display things like digital busses or states similar to a logic analyzer display. The input for this would be a X value, text to display, background color, and text color--although some of the examples below would require a boolean for a "empty" state (a middle line). The output visually would look like some of the examples below. Ideally it would also support getting hovered state to display extra information.

An enhancement similar to #292 would pair nicely with this, as seen in many of the below examples.
