✏️ Description

Creating new methods regarding sync success and failures for users to be able to act upon result.
Matching listener style from ios side
ios merged pr: Iterable/iterable-swift-sdk#988

We should move notifySyncSucceeded() inside the try block, and add a notifySyncFailed(e.message) to the catch. So it matches iOS behavior exactly: parse errors won't falsely report success.

Suggested change

	try {
	processEmbeddedMessagesResponse(data)
	} catch (e: JSONException) {
	IterableLogger.e(TAG, e.toString())
	}
	notifySyncSucceeded()
	try {
	processEmbeddedMessagesResponse(data)
	notifySyncSucceeded()
	} catch (e: JSONException) {
	IterableLogger.e(TAG, e.toString())
	notifySyncFailed(e.message)
	}

Agree with @joaodordio

Also is the refactoring really necesssary. Any refactor runs the risk of introducing regressions. Lets try to get the minimum changeset that accomplishes the task and has no side effects.

Yes i think we should have android and ios matching, this change introduces no behavior change, it is only new callbacks
