[examples] Added: textures_sprite_stacking example

[RobinsAviary]

A technique from GameMaker, decided to make an example of it for Raylib! I hope this is useful :) Model is not mine but is provided under [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/).

@RobinsAviary The example is cool but the image exceeds the supported texture size of some platforms, would it be possible to convert it into a square POT image?

I could convert it to an array of textures (or images) of each layer, if you think that would help overcome the issue, since that's what MagicaVoxel natively supports for export.

shoot i put my comment in the quote part lol. here's what i said:

I don't understand, do you mean multiple separate images? I'm afraid that's a worse solution...

Are those the only 2 export options provided by MagicaVoxel?

Just to clarify what you were referring to, was your idea closer to packing the texture in a POT image and then indexing it from that? I may be able to generate that using your texture packing tools but as far as MagicaVoxel is concerned, I believe those are the only image export options, sadly.

@RobinsAviary Ok, no worries, I'll merge as provided by MagikaVoxel but it could not work on web for now...
