Authentication Workflow

The authentication workflow is execute by a call to lastfm_auth() which invokes the full workflow:

1. fetch_request_token() creates a request token for the specific API request, this authenticates a particular API request and lasts for 60 minutes.

2. request_user_auth() launches a browser to request end-user authorization for access to user account data through the browser. The token created in the first step is provided as part of the user authorization request to associate the Application API Key with the user account providing authorization.

3. fetch_auth_token() fetches a session token to be used with all end-user requests. This is done by providing the application API key and the request token. The endpoint returns an encrypted session token that can be attached to all user requests.
