Subject: [PATCH] Add method KeyPair::public_key

Currently to get the `XOnlyPublicKey` from a `KeyPair` users must do
`XOnlyPublicKey::from_keypair(&kp)`. While this does the job we can make
the lib more ergonomic by providing a method directly on `KeyPair` that
calls through to `XOnlyPublicKey::from_keypair`.

Add method `KeyPair::public_key(&self)`.
