Typing on the get_unverified_header function

[lindycoder]

Hello, thank you for the tool!

It seems the get_unverified_header is missing types to use in a strict mypy configuration!

https://github.com/jpadilla/pyjwt/blob/master/jwt/api_jws.py#L202

If I am not mistaken, this might do it:

def get_unverified_header(self, jwt: str) -> Dict[str, Any]:

[lindycoder]

Actually based on what _load takes, jwt should be a Union[str, bytes]

Removing stale just waiting for a maintainer to comment if this issue is valid or not.

lgtm, can you open a PR?

Thanks, I might look into it, might take a couple weeks though, pretty busy
