FixedSizeBinary.Value applied the physical slice offset before validating the logical index. On sliced arrays, negative and one-past-the-end indexes could therefore expose adjacent values from the shared backing buffer.
This adds the standard array bounds check before applying the physical offset and covers valid, negative, and one-past-the-end access on a sliced three-element array.
