Evaluate UI Sounds for 1.2 release

Self-assigning to review the sim on main with supportsSound=true. If there is good coverage, we should consider publishing 1.2 with UI sound.

Overall, there is good coverage of UI sounds with supportsSound=true, but it would require some additional work to be publishable.

• All draggable objects need the grab/release sound, which requires the use of SoundDragListener.
• The wavelength slider is missing sounds, so I suspect the sim isn't using SpectrumSlider or if it is, that SpectrumSlider isn't inheriting UI sounds from Slider.
• The click interval of the Index of Refraction slider is too infrequent. Let's change the interval to 0.05.

@samreid I'm not sure how much work these issues would take to address. If on the lower-effort side, it seems worth doing for this release. Otherwise, we should defer until the next release.
