Support for split layers

Closes: ostreedev#69 This is initial basic support for splitting files (objects) from a commit into separate container image layers, and reassembling those layers into a commit on the client. We retain our present logic around e.g. GPG signature verification. There's a new `chunking.rs` file which has logic to automatically factor out things like the kernel/initramfs and large files. In order to fetch these images client side, we now heavily intermix/cross the previous code for fetching non-ostree layers.
