Install postback handle example

[egorlitvinenko]

Great implementation example, thank you!

Are you going to implement an example for handling postbacks too?

Hi @egorlitvinenko - thanks! glad you found this useful. as for postback handling, we are not planning an example at this time - but thanks for the suggestion. :)

Receiving and verifying the postbacks is relatively straight-forward though, documented by Apple here: https://developer.apple.com/documentation/storekit/skadnetwork/verifying_an_install_validation_postback
