1) `parquet-cpp` does not implement filtering (predicate pushdown). Clients such as Vertica, read the statistics from the metadata and implement their own filtering based on these stats.
Therefore, the read path does not require any changes. We should document that the min/max value can potentially contain NaNs.

2) I made changes to the write path to ignore the NaNs.
