feat: authorization request

[karimStekelenburg]

This PR adds functionality to make a request an access token using the scope parameter. Access token requests using the authorization_details parameter are currently not supported. It also adds a utility method to the OpenID4VCIClient class to construct and encode an authorization URL (the URL that points can be used to redirect the user to a login screen).
