Bug -> there are times during share partition initialization, where the
persister read state response contains batches, eg -
startOffset = 10, stateBatches = {{15, 20}, {30, 40}}
These gaps could natural gaps, but could also be batches which were fetched
before but were not acknowledged. In that case, these records must be made
available again for fetch.
This PR introduces another class variable, `gapsAfterInitialization`, which
stores the first offset of all these gaps in the read state response. The
`nextFetchOffset `method then consider these gaps as well while finding the
next offset to fetch from.
