Use an animated WebP or GIF for animated lock images

[byugoi]

Instead of needing to create a texture file and mcmeta file, being able to also use an animated WebP/GIF for the lock image would be a much easier experience for the user

Could also just limit to WebP for simplicity since it's a better file format

Yet Another Config Lib seems to have the ability to load WebP/GIF files, I will take a look at some point and if I think its suitable I might ask for permission to use it in this mod.
