As of ieee754 1.0.3, NaN is now encoded with one filled mantissa, which is in-spec but made a test fail.
According to the RFC for CBOR the canonical format for NaN should be 0xf97e00, which was the previous result. The encoder is not following canonical format - it will produce indefinite length lists and maps if it is more efficient -, but a value must be chosen to make the encoder consistent, so this is now being used.
