Remove url.parse (#148)

This handles the following deprecation in NodeJS by using the URL class rather than the global `parse` method which both have the `pathname` attribute which is what is required here.

[DEP0169] DeprecationWarning: url.parse() behavior is not standardized and prone to errors that have security implications. Use the WHATWG URL API instead. CVEs are not issued for url.parse() vulnerabilities.
