Decode a part from its CBOR array as the reference's minicbor decoder
does: a five-element array of four u32s, each with a head of any width,
and a definite-length byte string. Trailing bytes are ignored and a
seqNum of 0 is accepted.
InvalidParameter for a non-Uint8Array; Decoder with the reference's text otherwise: "decode
error: invalid CBOR array length", "unexpected type at position
: expected ", " overflows target type at position :
when converting u64 to u32", or "end of input bytes".
