decodeBytes(withMinimumLength:)

Decode bytes from the decoder. The length of the bytes must be greater than or equal to the length parameter. If the result exists, but is of insufficient length, then the decoder uses failWithError to fail the entire decode operation. The result of that is configurable on a per-NSCoder basis using NSDecodingFailurePolicy.
