Add sounds for the wavelength sliders

[jbphet]

The parent issue for this is #138.

The first screen of Color Vision has two sliders for controlling wavelengths, see the screenshot below. We should add sounds for these.

@Ashton-Morris created the following mockup for this:

- Color_Vision_Mockup_Single_Bulb_Filter_Color_Options_On_Pause_3_Types.mp4 This video has three base sounds that play when you move the filter color slider. This would only work when the sim is paused if we implemented it. But I am playing the whole spectrum of the sounds and then they are going through a bandpass filter which looks a lot like the filter on the color spectrum.

Assigning to @Ashton-Morris for a bit more design work. Once we've agreed on an initial direction, I'll start implementation.

As of 8/30/2022, work on adding sound to this simulation is being paused. I'll mark this issue as deferred, and we will hopefully return to it in the future.
