add support for security sticks, e.g. Yubikey

I tried to put the signing key onto my Yubikey 5c using PIV slot 9c:

$ ykman piv keys import 9c ~/.minisign/minisign.key
Enter a management key [blank to use default key]: 
Enter password to decrypt key: 
Wrong password.
Enter password to decrypt key: 
Aborted!

The correct password is not accepted. Perhaps this is an issue of ykman, but I just wanted to let you know too.

The ykman tool is very unlikely to encrypt and decrypt keys the same way as minisign.

FYI, we have a proposal from the community to implement hardware key-backed minisign signatures via a custom CTAP2 command (FIDO extension) for the Solo 1 device.

Hey, is there a link to the proposal or any information about its current state?

Talking about solokeys/solo1-cli#137, but it's not currently active. Also starting to get off-topic for this repo :)
