v5.5.4 - stablize InstallReferrer, misc fixes

5.5.4

• fix: memoization of static boolean return values (@jmheik)
• fix: add mac catalyst compatibility to getCarrier (#973) (thanks @robertying!)
• fix: add wider exception handling in install referrer (thanks @jmunozDevsu!)

Also the example is updated to react-native 0.62, works fine in my testing iOS + android

Enjoy!
