Currently, the `Item` type of `list::CursorMut`'s `Iterator` impl is `&mut T`. This is incorrect, as it allows the items to be moved out of the list without unlinking them. Instead, the iterator's item type must be `Pin`ned. PR #209 made this change for the `IterMut` type, but did not make the same change for `CursorMut`, so this commit fixes `CursorMut` similarly. BREAKING CHANGE: This changes the type signature of the `Iterator` impl for `list::CursorMut`.

This branch adds an immutable cursor to `cordyceps::list`, in addition to the existing mutable cursor. This functions similarly to the `std::collections::linked_list::Cursor` type. Depends on #240.
