Subject: [Haskell-beginners] Show encoded string of JWT / Crypto.JWT

Hello-

I am working with this package:
I created a `SignedJWT` object, but cannot find a way to print it in the standard string form. I mean the string that would be used by clients, for example to send it in the "Authorization: Bearer ..." header of a HTTP request. Like this one: "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c"

ghci> jwt <- ... -- some code
ghci> :t jwt
jwt :: Either JWTError SignedJWT
ghci> show jwt
