Add `Ref::new_known_layout_name_to_be_bikeshedded`. This is a private constructor which takes a `T: ?Sized + KnownLayout` bound. Before we make `KnownLayout` public, we will make it public and settle on a final name. Also add the ability to dereference a `Ref`, requiring the caller to promise bit validity. Refactor `TryFromBytes::try_from_ref` to use this instead of calling `Ptr::as_ref` directly, allowing `try_from_ref`'s internal safety comments to be significantly simpler. This machinery can be re-used to add APIs with a `T: ?Sized + KnownLayout + FromBytes` bound which allow for safe dereferencing. Makes progress on #29
