Allow middleware to be used in a gRPC environment

Thanks for filing this issue, and apologies for our delay in replying.

We'd definitely like to explore supporting gRPC in some manner in this library but I think given the changes that might require we'd look to potentially restructure this package and cut a new major.

For now it might be best to maybe document the existing usage of jwtValidator.ValidateToken you've described similar to the gin example we have in the repo, demonstrating how to create an interceptor for grpc-go that extracts a token and validates it.

We maintain an examples folder in the repo that would be the place to add it. You can check out one of the other folders in there as an example of the structure that should be followed

@mthssan-toast Hey! I haven't been able to put the example together, but I'll do my best to get to it in the next few weeks.

Thanks for the reply, @ewanharris. Sorry for the delay on my response as well!

That's not a bad idea. I was able to implement this flow at my company, but just results in some duplicate code since we have both http and grpc flows. I'll try to pick this up when I get a moment.

If I were to put up a PR for this documentation, where should this be added? Thanks.

@kingscott Hi there! Were you ever able to put together an example of how to use this middleware in a gRPC environment?

Submitted a PR here: #244. Let me know if there's anything else you'd like to see here @ewanharris. I tried to be as explicit as possible.
