Add a CenterCropTransformation

[ghost]

Reference: https://github.com/bumptech/glide/blob/d8278f43a94484f20822170b71ac7b66269a2aa6/library/src/main/java/com/bumptech/glide/load/resource/bitmap/CenterCrop.java

Sometimes in some combination transformations, it is possibly important

I'd like to avoid adding new transformations to the base coil artifact. I'd check out https://github.com/Commit451/coil-transformations, which is the Coil counterpart to glide-transformations and already has support for a center crop transformation.

@colinrtwhite I think these should be built into the coil because it is the basic conversion, such as centerCrop, fitCenter

@VVVenom If you're loading into an ImageView Coil will automatically detect its scaleType and load the image at the correct dimensions so it fits/fills the view.

If I set the background for the View, I should use CenterCropTransform(viewHeight: Int, viewWidth: Int) / CenterCropTransform(view: View)

Obviously this is useful in certain situations.

@colinrtwhite What will happen if my imageView has, for example, scaleType = fitCenter and I add transformations(CircleCropTransformation()) via code. Will both of them be applied or only fitCenter will?

Crop will be useful, because without it the base transformation RoundedCornersTransformation can't be used as desired:
A big image with RoundedCornersTransformation added and centerCrop set in ImageView will lead to no rounded corners because ImageView will crop them. And to prevent this we need another library with crop or other method of adding rounded corners to our ImageView. This is not what someone expects from bulletproof library ;) (Nice library, btw, thanks!)
