How can I read signature from a packet::write_packet result?

I learned about generating a signature packet in the document, but I cannot get that packet back into a Signature type.

I tried to use Signature::from_slice(Version::New, &sig_data), but it failed with Pgp(ParsingError(MapOpt)).

If you are interested, this is my failed test:

I managed to resolve it by using PacketParser, the code seems ugly but it finally worked!
