Request btrfs-assistant be added to Aurora image

I currently have btrfs-assistant layered but it would be great if it was in the image. Fedora/Aurora installs btrfs filesystem by default, so it makes sense to have this tool available in the desktop. This is the only package that I have layered, so getting it in the image would allow me to toggle off the rpm-ostree layering support and go with bootc instead.
