[Suggestion] Block animations

[mhay10]

I'm not sure if it's worth implementing but it would be cool if you could create an animation of block moving so you could create animations of redstone contraptions like piston doors, railways, etc.

Currently you can create an animation outside of the mod/game by doing /tick freeze and create a PNG file for every tick using /tick step then /isorender area. You can then use a tool like ffmpeg to create a gif/video of the series of PNG files to create an animation. The problem with this process is that exporting the images for every tick takes a long time since you have to manually save every frame of the animation.

The easiest way to implement this I though of was to add a command that allows exporting a render without viewing the render first so using something like AutoHotKey could script the commands out:

• Ex: /isorender render area <area params> <output filename - optional>
