> If the page header states that there are more values than are actually
> present in the page, the Parquet CPP can loop forever. This is because
> HasNext() will return true but the actual ReadBatch() will have nothing to
> read and will not change reader state, causing an infinite loop. We first
> noticed the bug via ScanFileContents(), but this impacts any code that does
> not check to see if ReadBatch() consumed anything.
