Fixed reading multiple parquet pages.

[jorgecarleitao]

There was a mistake from my part in computing the remaining number of elements when reading parquet pages that caused the skip of the last elements of the last page. :/

Thank you very much to @vincev for reporting this at #373 .

Closes #373

PS. I will be working in creating random tests to make us a bit more resilient on large scale parquet files created by external sources.
