New deregistration metadata format (CIP-0036)

The PR was merged today, now there is a proper way to define a deregistration via CIP-0036 too.

Will not see a workable backend until Fund 11 (maybe Fund 10 but not very likely).

Just wanted to point it out here. Cardano-Signer starting with version 1.9.0 will support the added key 61286 and its format.
