Function openpgp_card_sequoia::upload_from_cert_yolo

pub fn upload_from_cert_yolo(
    oca: &mut CardAdmin, 
    cert: &Cert, 
    key_type: KeyType, 
    password: Option<String>
) -> Result<(), Box<dyn Error>>

Convenience fn to select and upload a (sub)key from a Cert, as a given KeyType. If multiple suitable (sub)keys are found, the first one is used.

FIXME: picking the (sub)key to upload should probably done with more intent.
