Currently this is a rough rebase of work done by @ggershinsky. As ParquetMetaDataReader is now available some refactoring will be required.

@rok let me know if you want any help shoehorning this into ParquetMetaDataReader.

@etseidl could you please do a quick pass to say if this makes sense in respect to ParquetMetaDataReader?
I'll continue with data decryption.

Only looking at the metadata bits for now...looks good to me so far. Just a few minor nits. Thanks @rok!

I'm not sure we should be updating a deprecated function. If encryption is desired I'd say force use of the new API so we don't have to maintain this one. Just pass None to ParquetMetaDataReader::decode_metadata.

Very minor nit: I understand that file_decryption_properties needs to be cloned eventually...just wondering if we could pass references down into decode_metadata and do the clone there where it's more obviously needed.
