Look into the feasibility of adding a new filter for parquet file format

Support for the parquet file format has been requested on the LibreOffice mailing list several times.

We could supposedly make use of the Apache Arrow library to avoid having to implement the new filter from scratch. We need to look into this library to figure out the difficulty of integrating it into orcus. Depending on the API design of the Arrow library, it may or may not make sense to integrate it into orcus. We will need to make the determination as part of this investigation.

Note that this is an investigation ticket to assess the feasibility of adding support for the parquet file format. If we decide to implement this for real, we'll create another ticket for the implementation.
