> [C++] Add column selection to parquet::arrow::FileReader

> With multithreaded reads coming in PARQUET-835, it would be better to push
> down the subsetting into the FileReader rather than leaving this work at the
> application level. One artifact of this is the Python interface in Arrow
> (which handles subsetting in Python/Cython)
