seq_id generation using bason lib should be inside the persistence sdk not here. this is part of persistence

By the design currently the seq id, sync token and pagination is currently being updated inside the contentstack-ios project. This is why it was deemed to be added here and not in persistence package. Please let me know your thoughts on it.

Thanks

The function should be named initSeqSync or initialSequenceSync.

Reasoning: Including "id" in the function name may cause confusion for developers as it doesn't serve any purpose in this context. This function doesn't require any input from the developer.
