Add a new option, `--require-digest`, to `bootc upgrade` and `bootc switch`. When provided, bootc checks that the image to be downloaded/staged has the given digest; if it does not, the operation will fail with an error message. This is useful for avoiding TOCTOU issues when performing some external checks (such as provenance verification) on an image before updating to that image.
