Issue summary

From your readme you call:

...
SwiftyStoreKit.verifySubscription(... productId: ...}
...
}

What to do if we don't know this productId and have multiple subscriptions which may vary?

What did you expect to happen

Get any valid subscription from the request result without of binding to concrete Id?

What happened instead

The app don't have to know productId but the result contains info about this subscription. Why must I know productId to check if just ANY subscription from list is valid?

Research direction
This issue requests a method to verify any valid subscription without a specific productId. The existing `verifySubscription` requires a productId. A new method could accept an array of productIds or return all active subscriptions from the receipt. Look at the `verifyReceipt` and `verifySubscription` functions in the SwiftyStoreKit source code, and consider how to iterate over receipt's in app purchases to find valid subscriptions. The discussion in the issue suggests providing a list of product IDs or a wildcard. Implementing this would involve parsing the receipt's `latest receipt info` and checking expiration dates for each product. No linked PRs exist.
