The PR handles slicing of fetched records based on acquire response for share fetch. There could be additional bytes fetched from log but acquired offsets can be a subset, typically with `max fetch records` configuration. Rather sending additional bytes of fetched data to client we should slice the file and wire only needed batches. Note: If the acquired offsets are within a batch then we need to send the entire batch within the file record. Hence rather checking for individual batches, PR finds the first and last acquired offset, and trims the file for all batches between (inclusive) these two offsets.
