Add support for transformations in coil-gif

Is your feature request related to a problem? Please describe. Right now I want to use coil’s coil gif extension together with transformations, it seems that Gif extension is ignoring them

I did:

Coil.setDefaultImageLoader(ImageLoader(this) {
            componentRegistry {
                add(GifDecoder())
            }
        })

and load image with:

imageView.load(R.drawable.some_gif_image) {
                placeholder(R.drawable.placeholder)
                transformations(CircleCropTransformation())
                repeatCount(0)
            }

Describe the solution you’d like Gid extension should apply transformations

The release is delayed slightly, unfortunately as I haven’t been able to solve the issue on master yet. In the meantime you can use the snapshot builds if you need the latest changes now.
