Deserialize IdentityKey

[cremfert]

I'm trying to deserialize an identity key that I stored in a file. For this, I used .serialize the key and then, to load it again, I use the IdentityKey.fromBytes method.

Here is a parameter required called offset. Is this always 0 or does it have a different meaning?

Thanks a lot!

Seems like a redundant parameter here, welcome PR to fix this.

The offset means if it's a DjbECPublicKey has a type on the prefix.
