use typed ACS/transaction streams in quickstart-java examples

[S11001001]

• This example/quickstart-java template code from our Java quickstart should be able to use typed ACS and transaction streams for Java codegen #14969 for both ACS and transaction stream parts:

daml/docs/source/app-dev/bindings-java/quickstart/template-root/src/main/java/com/daml/quickstart/iou/IouMain.java

Lines 60 to 99 in b7fccfc

	client
	.getActiveContractSetClient()
	.getActiveContracts(iouFilter, true)
	.blockingForEach(
	response -> {
	response
	.getOffset()
	.ifPresent(offset -> acsOffset.set(new LedgerOffset.Absolute(offset)));
	response.getCreatedEvents().stream()
	.map(Iou.Contract::fromCreatedEvent)
	.forEach(
	contract -> {
	long id = idCounter.getAndIncrement();
	contracts.put(id, contract.data);
	idMap.put(id, contract.id);
	});
	});
	Disposable ignore =
	client
	.getTransactionsClient()
	.getTransactions(acsOffset.get(), iouFilter, true)
	.forEach(
	t -> {
	for (Event event : t.getEvents()) {
	if (event instanceof CreatedEvent) {
	CreatedEvent createdEvent = (CreatedEvent) event;
	long id = idCounter.getAndIncrement();
	Iou.Contract contract = Iou.Contract.fromCreatedEvent(createdEvent);
	contracts.put(id, contract.data);
	idMap.put(id, contract.id);
	} else if (event instanceof ArchivedEvent) {
	ArchivedEvent archivedEvent = (ArchivedEvent) event;
	long id =
	idMap.inverse().get(new Iou.ContractId(archivedEvent.getContractId()));
	contracts.remove(id);
	idMap.remove(id);
	}
	}
	});

• and this can be removed:

• extend Typed ACS and transaction streams for Java codegen #15159 with any further useful utilities to make this nice
• smoketest "Tests for quickstart-java" from the release process
• update all the line numbers in quickstart doc to match their current appearance on docs.
