Adding Bloom filter to small Parquet file bloats in size X1700

Converting a small, 14 rows/1 string column csv file to Parquet without bloom filter yields a 600B file, adding '.withBloomFilterEnabled(true)' to ParquetWriter then yields a 1049197B file.

It isn't clear what the extra space is used by.

Attached csv and bloated Parquet files.
