The condition
readStartInBytes + readLength >= pageReader.byteLength
and the condition
definitionLevelsRead >= pageReader.currentPageCount
both were checking for the end of a page. I'm not sure if in the previous
code one condition could be true but not the other. In the new while loop, if
one is true, so is the other. So we need only one of the two.
