Identify encryption keys [enhancement]

[INCIBE-CERT]

It is possible to provide multiple encryption keys. For example:

shows current INCIBE-CERT PGP keys for incidencias@... and cert@... email addresses but there is no information shown other than the fingerprints 51278C466B8657B62661C2C39699FDB2EC855918 and C50CD6F58E6D513AF09547E4EB5BA6FCEB9A069A (without inspecting the actual OpenPGP keys with another tool), while they are two keys with different purpose.

I would expect cerebrate to show the uid somewhere. At least, one of the uids, when the key has multiple ones.

(note: you can find these keys published on https://www.incibe.es/en/incibe-cert/about-us/pgp-public-keys)
