Title: jwt.ValidationError didn't not implement error

I tried to type assert the err from jwt.Parse() and got this

```
./main.go:135: impossible type assertion:
jwt.ValidationError does not implement error (Error method has pointer receiver)
```

this fixes it and makes the Errors field accessible.
