v3.3.0

• Add option to track GCLID (Google Click ID) as a user property (set includeGclid to true in the SDK configuration).
• Add option to track new UTM parameters, referrer, and GCLID values during the same session. By default the SDK only saves the values once at the start of the session. You can remove this restriction by setting saveParamsReferrerOncePerSession to false in the SDK configuration. See the Readme for more information.
