6.3.0

* A new `anonymizer` object has been added to the `Insights` response model.
  This object contains information about anonymizing services and VPN providers
  associated with an IP address. Available from the GeoIP2 Insights web service
  only. The object includes the following properties:
  * `confidence`: A score (1-99) representing percent confidence that the
    network is part of an actively used VPN service
  * `isAnonymous`: Indicates if the IP belongs to any anonymous network
  * `isAnonymousVpn`: Identifies IPs registered to anonymous VPN providers
  * `isHostingProvider`: Flags hosting/VPN providers used for anonymizing
  * `isPublicProxy`: Identifies public proxy addresses
  * `isResidentialProxy`: Detects suspected anonymizing networks on
    residential ISPs
  * `isTorExitNode`: Identifies Tor exit nodes
  * `networkLastSeen`: The last day (YYYY-MM-DD) the network was sighted in
    our analysis of anonymized networks
  * `providerName`: The name of identified VPN providers (e.g., "NordVPN")
* A new `ipRiskSnapshot` property has been added to the `traits` object.
  This provides a risk score ranging from 0.01 to 99, with higher values
  indicating greater risk. Available from the GeoIP2 Insights web service only.
* The following properties in the `traits` object have been deprecated in
  favor of the new `anonymizer` object. These properties will continue to work
  but users should migrate to using the `anonymizer` object:
  * `isAnonymous`
  * `isAnonymousVpn`
  * `isHostingProvider`
  * `isPublicProxy`
  * `isResidentialProxy`
  * `isTorExitNode`
* Added the `status` property to `WebServiceClientError`. This property
  contains the HTTP status code when the error is the result of an HTTP
  response error. Network errors (timeouts, fetch errors) will not have a
  status code.
