Using a `KeyObject` for `signingKey` option doesn't work

[marcghorayeb]

Hi,

Contrary to what the typing describes, giving a KeyObject to the signingKey results in the following error thrown:

Error: The key option must be a string, a buffer, an object containing key/passphrase properties or a function returning the algorithm secret or private key.

Digging a bit deeper, this is coming from the fast-jwt parsing of that option here: https://github.com/nearform/fast-jwt/blob/master/src/signer.js#L219

Is the typing wrong or was functionality removed?

@marcghorayeb Line 206 does the check for the object syntax. I noticed fast-jwt is up to v4 and I was using v3. I'm going to do a release on latest version

I just published 11.7.0 using latest version of fast-jwt
