preload and async setup loading animation

[quinton-ashley]

@SableRaf I like this idea!

processing/p5.js#6795

I did something similar with p5play with the "made with p5play" screen but it fills the window, assuming nearly all usage of p5play is in global mode.

For q5, I'm thinking of doing a loading animation of the q5 logo spinning in css right above the center of the canvas.

In response to the opt-in idea, I think that wouldn't work because developers loading assets locally may never experience long loading times, so they wouldn't see the message suggesting to enable it. Also my assumption is a loading animation would always be preferable to "loading" text.

I agree with it being opt-out, but I think you should still be able to customize the loading animation. What are your thoughts on that?

yeah for sure, I'm thinking users could opt out like this:

Q5.preloadAnimation = false

Would need to be set before preload is run
