Previously when loading a PrivateKey into a DNSKEY we would return the PrivateKey with the PublicKey set from the DNSKEY struct. Now that behaviour is flipped and the PublicKey is taken from the PrivateKey and set in the DNSKEY.

It will now fail if the algorithm or PublicKey in the DNSKEY doesn't

I added a new entry and my editor reformatted the code to align better. I thought it an ok change so I kept it, but I can take this out if needed.

what motivates this change?

I have private keys stored in a database and I need to load those, get the public key from it and also use that to create the DS. The previous version took the public key from the DNSKEY object and then copied it into the private key. To me it makes more sense to just keep the public key stored inside the private key (and it also serves my needs to be fair).
Also this change makes it simpler to load a private key, since an almost empty DNSKEY object can be used to load the private key.
