Support writing bloom filter metadata #105

For high-cardinality columns, writing Bloom filter metadata helps readers push down predicates more efficiently. By default, pg_parquet enables dictionary encoding, which also improves predicate pushdown but can significantly increase file size when cardinality is high. To address this, we may introduce options to disable dictionary encoding and enable Bloom filter metadata instead.
