Yubikey 5ci Issue (fixed in piv-go upstream)

[grempe]

I am having an issue with a Yubikey 5ci on macOS 10.15.5. The output in the yubikey-agent.log says:

❯ cat /usr/local/var/log/yubikey-agent.log
Connecting to the YubiKey...
agent 13: failed to prepare private key: parse attestation cert: parsing extension: unrecognized formfactor: 0x5

This seems to have been resolved in a commit upstream in piv-go (see link below). I don't think its included in latest release that has been cut for that repo though. Can a new version be cut and pulled in and a new release of yubikey-agent cut?

go-piv/piv-go#62

The issue in #32 has the same output and it might be a related issue, but the submitter of that issue didn't include the log output so I can't be sure its the same.
