This commit makes Renames `WalletBirthday` to `Checkpoint` and makes Checkpoint an internal type. Public ocurrences of this type is replaced by `BlockHeight` (Int) and then retrieval of the Checkpoint is deferred to the appropiate place in the code Add an extension method to `BlockHeight` to get latest checkpoint height present in the SDK's bundle PR Suggestions: Add test for integer overflow on JSON File renamed from WalletBirthday to Checkpoint
