v0.6.0

• Add support for client cloning (useful when trying to re-use EasyVCR's HTTP client as an inner client inside multiple HTTP clients)
  • This avoids an error where some clients, like RestSharp, expect the inner client to be a new instance each time
• EasyVCR now uses an EasyVCRHTTPClient class instead of HttpClient to allow for internal functionality
  • EasyVCRHTTPClient implements HttpClient, so it can be used anywhere a HttpClient is expected
