Re: [PR] PARQUET-3479: Add configuration to disable early dictionary compression check [parquet-java]

   @Fokko Could you take a look? This adds a config (`parquet.dictionary.early.check.enabled`) to disable the first-page compression check in FallbackValuesWriter. With modern page-index defaults (~20k rows/page), the check fires too early for moderate-cardinality columns, abandoning dictionary encoding prematurely. Includes unit test + E2E integration test writing real Parquet files. Thanks!
