Perform message type-checking & optional certificate loading.
This includes fast-forwarding cert ``msg`` objects past the nonce, so
that the subsequent fields are the key numbers; thus the caller may
expect to treat the message as key material afterwards either way.

it was (e.g. ECDSA.)

Supplement the private key contents with data loaded from an OpenSSH
public key (``.pub``) or certificate (``-cert.pub``) file, a string
containing such a file, or a `.Message` object.
The .pub contents adds no real value, since the private key
file includes sufficient information to derive the public
key info. For certificates, however, this can be used on
the client side to offer authentication requests to the server
based on certificate instead of raw public key.
See:
https://github.com/openssh/openssh-portable/blob/master/PROTOCOL.certkeys
Note: very little effort is made to validate the certificate contents,
that is for the server to decide if it is good enough to authenticate
successfully.

Most of the time you'll want to call `from_file`, `from_string` or
`from_message` for useful instantiation, the main constructor is
basically "I should be using ``attrs`` for this."
