---------------------------------------------------------------
Is this a matter of implementing the ParquetReader as shown in [https://github.com/apache/arrow/blob/723a437802143fd00d97c101caaf6deabea3f8c6/cpp/examples/parquet/low-level-api/reader-writer.cc#L181]
into the list of IO types for the R package?
[https://github.com/apache/arrow/blob/master/r/src/io.cpp#L110]. I think if the ParquetReader is implemented, it could create a arrow::Table type just like RecordBatchFileReader, and then we would be able to reuse the table to tibble conversion function that already exists
