Describe the problem you'd like to have solved

Popular cloud providers e.x. AWS + Google provide APIs for key signing that allow for asymetric encryption without the private key being accessible to code. It would be nice to be able to create JWTs with such APIs using this library.

Describe the ideal solution

There are different approaches to solving this but I think the right level might be to have some set of options like:

{
  alg: 'RSA256',
  pub: '...',
  sign: signFunc,
}

I read through the comments in issue #427 which makes me think that it would be best to force usage of wellknown algorithms but provide a way to use third party key apis.

Alternatives and current work-arounds

Currently one would have to rebuild the entire signature code which is error prone.

Additional context

I'm happy to provide a pull request if we can agree on APIs
