Is your feature request related to a problem or challenge?

I'm trying to use DATAFUSION to load some parquet-encrypted files, but I can't find the option to set the encryption parameters (key, etc).

I found ParquetReadOptions, but it seems don't have a encryption options.

FWIW there is a parquet reader that supports encryption in comet that might serve as some inspiration / source of code https://github.com/apache/datafusion-comet/tree/main/core/src/parquet

This should now be supported by #16351

See example test here: https://github.com/apache/datafusion/blob/0ae9fdcb0da0cfaf180848115705fe3a9b7de343/datafusion/core/tests/parquet/encryption.rs
