Golang AWS Cognito Validate JWT token

	/* This algorithm is based off of the AWESOME gist by miguelmota:

	https://gist.github.com/miguelmota/06f563756448b0d4ce2ba508b3cbe6e2

	However that code had two problems -

	1) It used a deprecated jwt library (github.com/dgrijalva/jwt-go). The code below uses the current implementation at github.com/golang-jwt/jwt/v4

	2) The KeyFunc closure passed to jwt.Parse() always used the second JWK, even if the KID in the JWT header pointed to a different JWK. The code below finds the JWK for the KID specified in the header and verifies against that.
