A selector that selects the range of data returned by a list operation on a [`Deno.Kv`](../././~/Deno.Kv). The selector can either be a prefix selector or a range selector. A prefix selector selects all keys that start with the given prefix (optionally starting at a given key). A range selector selects all keys that are lexicographically between the given start and end keys.
