Support indicating EV certificates

[speshak]

It would be nice if dump & connect would indicate if a certificate is an Extended Validation certificate.

If you run with --verbose, certigo will already show you EV fields in certificates.

For example:

$ certigo connect --verbose squareup.com:443 | grep EV
	EV Incorporation Country: US
	EV Incorporation Province: Delaware
	EV Incorporation Registration Number: 4699855

It will also show fields like Organization, Business Category, etc. that are relevant to EV certificates.

Oh, indeed it does. Sorry for the noise.
