Animated Stacked Sprites

[caoakleyii]

Description

Added the ability for sprit3r to play and test animated stacked sprites.

It uses the existing quads table, adding all the quads to it, and displays certain quads as a stacked sprite, depending on the animation frame.

Here's a test file

Here's a quick demo of the animation running within sprit3r

This is really cool addition, awesome that people are still using sprit3r!
Perhaps a slider to change the animation speed could be a nice improvement too?

As you probably noticed I'm not actively maintaining this repo anymore, so if you plan to work more on this I could add a link to your fork in the readme if you want? Would make the process of updating everything a bit easier!

I'll merge this when I have a bit more time to test everything!

@evgiz I do have a version of this on my fork (not pushed to the repository yet) with the ability to set animation frame speed, and also toggle off/on the auto updater.

I've found that as the file sizes grow with animations, the animation gets a bit jumpy every 0.5s because of the updater.

I'll clean up that code and work on updating this PR with that over the weekend.

I'll see if I have anything else planned to add before I'd recommend updating your README.
