Readme

DataFrame.IO.Parquet — pure-Haskell Parquet 2.0 reader and writer (with snappy, zstd, gzip codecs, dictionary decoding, nested list/repeated columns, and predicate pushdown). Heavy package — pulls in pinch, streamly, and compression codecs. Reading directly from HuggingFace (hf://) datasets lives in the separate dataframe-huggingface package. Most users want dataframe-csv instead unless they specifically need Parquet.
