[Feature request] Remove hint stickers in 2D View for 3x3

[ThatKanjiJew]

Goal

I’d like to use Twizzle Editor’s 3x3 in 2D view without the hint facelets.

Possible solution

A useful solution would be fixing the Hint Facelets button in the Playback Options menu so that when disabled, it would hide the hint facelets.

Alternatives

No response

This wouldn't be too hard to implement for 3×3×3, but I'm a bit wary of introducing something that will be hard to generalize. Could you describe what use case this would support?

[lgarron]

Just some notes about how I'd implement this:

1. Add a hint-facelets class to some SVG elements.
2. Use CSS to set .hint-facelets { display: none; }.
3. Hook up listeners to toggle the CSS based on the hintFacelets prop.
