1.9.0

Adds a new legacyProductsIDsByTier parameter you can set on FreemiumKit.shared upon app start if you have legacy products on App Store Connect that are no longer part of your paywall, to maintain access for existing customers. This is only needed if you historically had a different set of subscriptions/lifetime purchases and created new ones at a later time. If all your products you ever released are currently on your paywall, you don't need this.
