What would you like to happen?

Currently, the reader for PulsarIO used the Reader interface to manually handle the cursors in the ReadPulsarDoFn and it does not have the option to acknowledge the messages. So I am raising this issue to have this TODO and allow the user to set the acknowledgment of messages and implement and analyze the acknowledgment of the messages may be in batch or each time a bundle inside DoFn is done (this should be to be taken for analysis)
