ssh: sign and verify

[caarlos0]

Initial implementation of proposal of SSHSIG
closes golang/go#68197

Want to make sure the API is all right before
adding more tests.
Also seeking feedback on how to best test
this - is it OK to sign and verify in the
same test, or do you have other ideas?
Maybe a fixed rand reader?

PS, usage would be something like this:

const ns = "my@namespace"
const data = "the data to be signed"

// to sign:
signer, _ := ssh.ParsePrivateKey(keypem)
signature, _ := ssh.Sign(signer, rand.Reader, []byte(data), ns)

// to verify:
pub, _ := ssh.ParsePublicKey(pubkeypem)
block, _ := pem.Decode(signature)
err := ssh.Verify(pub, []byte(data), block.Bytes, ns)
