+- Incrementally moving towards using `Span` for the `Reader` and `Writer` traits. Added an `_read` function to `Reader` and `_read_at` to `ReaderAt` traits to enable reading into `Span`. The usual implementation is the take a `List[UInt8]` but then to use `_read` and pass a `Span` constructed from the List.
