OAuth 1.0a Access Token Acquisition with OAuthlib

This function uses the oauth1 module from the OAuthlib library to create an OAuth 1.0a client and obtain an access token through the client. The function accepts client key, client secret, token key, token secret, and URL as parameters, then sends a signed POST request to the token endpoint, and finally parses the response to obtain the access token.
