Review Comment:
If two batches have the same timestamp, and both timestamps are greater than
`maxTimestampSoFar`, and the first batch is skipped due to
`indexIntervalBytes`, the resulting index for searching the 'earliest offset'
of the maximum timestamp using `TimestampSpec` will be incorrect.

Review Comment:
`shallowOffsetOfMaxTimestamp` is useless, so could you please remove it also?
