Node ids are pubkeys, but we only use them as pubkeys for routing and checking gossip messages. So we're packing and unpacking them constantly, and wasting some space and time. This introduces a new type, explicitly the SEC1 compressed encoding (33 bytes). We ensure its validity when we load from the db, or get it from JSON. We still use 'struct pubkey' for peer messages, which checks validity.
