aws-jwt-verify v3.0.0 Released

What started as pull request #60, escalated to becoming a maintainer on aws-jwt-verify and releasing v3.0.0.

AWS JWT Verify is a JavaScript library for verifying JWTs signed by Amazon Cognito, and any OIDC-compatible IDP that signs JWTs with RS256 / RS384 / RS512. I wanted to add web browser compatibility for a project I was working on. It was a nice return to using the Web Cryptography API as I had done in various presentations over the years.
