Peeks a batch of message.

Each client instance caches the last sequence number and unless explicitly indicated, uses that sequence number to peek the next message. For example, if you peek all messages in a queue (in batches, providing the fromSequenceNumber parameter), and then peek with no parameter, the method returns no messages.
