superwall/Superwall-iOS 4.16.0 on GitHub

Adds install attribution matching support. If you set up performance marketing integrations on the Superwall dashboard, the SDK will attempt to match the install and track an attribution_match event. The attribution properties will be added to user attributes so that they can be used as breakdowns and filters in the charts.
Adds support for annual subscriptions that are billed monthly.
Added EventTrackingBehavior enum and SuperwallOptions.eventTrackingBehavior property for GDPR-compliant event collection control. Use .all (default) to track everything, .superwallOnly to suppress user-initiated tracking, trigger fires, and user-attribute updates while keeping internal SDK events, or .none to stop all event collection entirely. The behavior can also be changed at runtime via Superwall.shared.eventTrackingBehavior.
Deprecated SuperwallOptions.isExternalDataCollectionEnabled. Setting it to false now maps to .superwallOnly; setting it back to true maps to .all.

Fixes a crash due to concurrent calls to preloadAllPaywalls.
Fixes an intro offer eligibility mismatch between the paywall and the payment sheet when upgrading/crossgrading/downgrading.
