synopsis: Parquet reader and writer for the dataframe ecosystem.
description:
@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@ 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.
