Using the clippy lint `unwrap_used`, we can automatically lint against all uses of `.unwrap()` on `Result` and `Option`. This turns up quite a few results actually. In most cases, they are invariants that can't actually be hit. For these, we change them to `Option`. In other cases, they can actually be hit. For example, if the user supplies an invalid log-filter. Activating this lint ensures the compiler will yell at us every time we use `.unwrap` to double-check whether we do indeed want to panic here. Resolves: #7292.
