Subject: [PATCH] Clarify hmacSampleSecret type

From looking at the godoc for this (https://godoc.org/github.com/dgrijalva/jwt-go#example-Parse--Hmac) it isn't clear what the type of hmacSampleSecret should be as you can't see the rest of this file. I ended up having to search through the code to figure out it needed to be a byte array.
