OAuth1 Access Token Retrieval using OAuthlib

This function uses the OAuthlib library to retrieve an access token by exchanging an authorization code obtained from OAuth 1.0. The function accepts client ID, client secret, token URL, and authorization response, then parses the authorization response, and uses an OAuth1 client with HMAC signature method to request the access token.
